Features(If you need a chip brochure please contact me) :
 
The SDLA12TA is a PWM switch-mode battery charger controller for 12V lead-acid battery in a small package using few external components.
The SDLA12TA is specially designed for charging 12V lead-acid battery with trickle charge, constant current charge, over-charge and float charge mode.
In over-charge and float charge mode, the regulation voltage is internally set. 
The constant charge current is programmable with a single sense resistor.
 
Deeply discharged batteries are automatically trickle charged at 17.5% of the programmed
constant charge current until the cell voltage exceeds 75% of the regulation voltage in
over-charge mode. The over-charge is terminated once the charging current drops to 38% of the
constant charge current, then SDLA12TA will enter float charge mode. A new charge cycle
automatically restarts if the battery voltage falls below 83.95% of the over-charge voltage in
float-charge mode. SDLA12TA will automatically enter sleep mode when input voltage is lower than battery voltage.
Other features include undervoltage lockout and status indication, etc.
 
 
The Regulation Voltage in Over Voltage Mode and Float Charge Mode 
The regulation voltage VOC at BAT pin in over charge mode is set at 14.8V(Typical) with ±1.5% accuracy.
In float charge mode, the regulation voltage VFLOAT at BAT pin is 91.57% of that in over charge mode, which is 13.55V(Typical).
Trickle Charge Mode At the beginning of a charge cycle, if the battery voltage is below 75% ×VOC, the charger goes into trickle
charge mode with the charge current set at about 17.5% of the constant current.
 
End-of-Over Charge Current
When the battery voltage approaches the over-charge voltage, the charger goes into the over charge mode. In
over charge mode, the charge current start to decrease and when the charge current drops to 38% of constant
charge current, the charger goes into float-charge mode.
 
Float Charge Mode
After the over voltage charge is terminated, the charger goes into float charge mode. In float charge mode, the
battery voltage is regulated to 91.57% ×VOC, namely 13.55V(Typical). Float charge mode can compensate for
the loss of battery power due to self-discharge or external loading.
 
Automatic Battery Recharge
In float mode, if both the battery and the input power supply (wall adapter) are present, a new charge cycle will
begin if the battery voltage drops below 83.95% ×VOC due to self-discharge or external loading.
A new charge cycle can also be started manually by plugging off the input supply and reapplying it.

Working principle: 
The water level rises: When the water level is lower than the ''Low level'', the water pump starts to supply water to the water tower; when the water level is higher than the ''High level'', the water pump stops supplying water.
Water level reduction: When the water level is lower than the ''High level'', the water pump does not work and the water level continues to decrease. When the water level is lower than the ''Low water level'', the water pump starts to supply water to the water tower.

Probe making
1 Prepare some wires (ordinary household wire and cable)
2 Strip the wires 10-20 mm at both ends
3 Connected probe (wire)

Features(If you need a chip brochure please contact me) :
 
The DD30CRTA is a PWM switch-mode battery charger controller for 12V lead-acid battery in a small package using few external components.
The DD30CRTA is specially designed for charging 12V lead-acid battery with trickle charge, constant current charge, over-charge and float charge mode.
In over-charge and float charge mode, the regulation voltage is internally set. 
The constant charge current is programmable with a single sense resistor.
 
Deeply discharged batteries are automatically trickle charged at 17.5% of the programmed
constant charge current until the cell voltage exceeds 75% of the regulation voltage in
over-charge mode. The over-charge is terminated once the charging current drops to 38% of the
constant charge current, then DD30CRTA will enter float charge mode. A new charge cycle
automatically restarts if the battery voltage falls below 83.95% of the over-charge voltage in
float-charge mode. DD30CRTA will automatically enter sleep mode when input voltage is lower than battery voltage.
Other features include undervoltage lockout and status indication, etc.
 
 
The Regulation Voltage in Over Voltage Mode and Float Charge Mode 
The regulation voltage VOC at BAT pin in over charge mode is set at 14.8V(Typical) with ±1.5% accuracy.
In float charge mode, the regulation voltage VFLOAT at BAT pin is 91.57% of that in over charge mode, which is 13.55V(Typical).
Trickle Charge Mode At the beginning of a charge cycle, if the battery voltage is below 75% ×VOC, the charger goes into trickle
charge mode with the charge current set at about 17.5% of the constant current.
 
End-of-Over Charge Current
When the battery voltage approaches the over-charge voltage, the charger goes into the over charge mode. In
over charge mode, the charge current start to decrease and when the charge current drops to 38% of constant
charge current, the charger goes into float-charge mode.
 
Float Charge Mode
After the over voltage charge is terminated, the charger goes into float charge mode. In float charge mode, the
battery voltage is regulated to 91.57% ×VOC, namely 13.55V(Typical). Float charge mode can compensate for
the loss of battery power due to self-discharge or external loading.
 
Automatic Battery Recharge
In float mode, if both the battery and the input power supply (wall adapter) are present, a new charge cycle will
begin if the battery voltage drops below 83.95% ×VOC due to self-discharge or external loading.
A new charge cycle can also be started manually by plugging off the input supply and reapplying it.

Description:
 
Low Noise, Regulated Charge Pump DC/DC Converter
2 in 1 DC-DC Step-Down & Step-Up Converter module
Fixed 3.3V -4% Output
Voltage Input Range: 1.8~5V
Long time maximum output current 100mA

working frequency 1.2MHz.
Short-Circuit Protection
No load input current : 0.65mA
Size 11mm x 7.6mm x 4.5mm(small)
Weight : 0.3g(Very very light)
  
The CE021is a low noise, constant frequency (1.2MHz) switched capacitor voltagedoubler.
It produce a regulated output voltagefrom a 1.8V to 5V input with up to 100mA of output current.Low external parts count (one flying capacitor and two small bypasscapacitors at VIN and VOUT) make theCE021 ideally suited for small,battery-powered applications.
   
The CE021 have thermal shutdown capability and can survive a continuous short circuit from VOUT to GND. Built-in soft-start circuitry prevents excessive inrush current during start-up.
  
High switching frequency enables the use of small ceramic capacitors. A low current shutdown feature disconnects the load from VIN and reduces quiescent current to <1uA.

Features(If you need a chip brochure please contact me) :
 
The DD30CRTA is a PWM switch-mode battery charger controller for 12V lead-acid battery in a small package using few external components.
The DD30CRTA is specially designed for charging 12V lead-acid battery with trickle charge, constant current charge, over-charge and float charge mode.
In over-charge and float charge mode, the regulation voltage is internally set. 
The constant charge current is programmable with a single sense resistor.
 
Deeply discharged batteries are automatically trickle charged at 17.5% of the programmed
constant charge current until the cell voltage exceeds 75% of the regulation voltage in
over-charge mode. The over-charge is terminated once the charging current drops to 38% of the
constant charge current, then DD30CRTA will enter float charge mode. A new charge cycle
automatically restarts if the battery voltage falls below 83.95% of the over-charge voltage in
float-charge mode. DD30CRTA will automatically enter sleep mode when input voltage is lower than battery voltage.
Other features include undervoltage lockout and status indication, etc.
 
 
The Regulation Voltage in Over Voltage Mode and Float Charge Mode 
The regulation voltage VOC at BAT pin in over charge mode is set at 14.8V(Typical) with ±1.5% accuracy.
In float charge mode, the regulation voltage VFLOAT at BAT pin is 91.57% of that in over charge mode, which is 13.55V(Typical).
Trickle Charge Mode At the beginning of a charge cycle, if the battery voltage is below 75% ×VOC, the charger goes into trickle
charge mode with the charge current set at about 17.5% of the constant current.
 
End-of-Over Charge Current
When the battery voltage approaches the over-charge voltage, the charger goes into the over charge mode. In
over charge mode, the charge current start to decrease and when the charge current drops to 38% of constant
charge current, the charger goes into float-charge mode.
 
Float Charge Mode
After the over voltage charge is terminated, the charger goes into float charge mode. In float charge mode, the
battery voltage is regulated to 91.57% ×VOC, namely 13.55V(Typical). Float charge mode can compensate for
the loss of battery power due to self-discharge or external loading.
 
Automatic Battery Recharge
In float mode, if both the battery and the input power supply (wall adapter) are present, a new charge cycle will
begin if the battery voltage drops below 83.95% ×VOC due to self-discharge or external loading.
A new charge cycle can also be started manually by plugging off the input supply and reapplying it.

This  RG-178 coaxial cable is ready to help you extend the capacity of your data infrastructure. Coaxial cable is a type of shielded, electrical conducting cable used to transmit analog and digital signals. The initials RG stand for Radio Guide and are used to describe different types of coaxial cable. RG-178 cables are most commonly used for transmitting high-frequency signals. As such, they are often employed for the purpose of cabling between Wi-Fi routers and antennas. The SMA male and SMA female connectors that terminate this cable are also widely compatible with many wireless network implements. SMA stands for SubMiniature version A and is a form of RF coaxial connector with 50 ohms impedance and a performance frequency of up to 18GHz. SMA connectors feature a screw-type coupling mechanism and are frequently employed in bulkheads and patch panels because of the their diminutive size. For a widely compatible, resilient addition to your data infrastructure, look no further than this RG-178 coaxial cable with SMA male to SMA female connectors.
