The CB06CRMA is a complete constant-current /constant voltage linear charger for coin batteries. The device contains an on-chip power MOSFET and eliminates the need for the external sense resistor and blocking diode. An on-chip adaptive block can adjust charging current automatically based on the output capability of input power supply, so CB06CRMAis ideally suited for solar powered system. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature.
The regulation voltage is internally fixed at 3.3V with 1% accuracy, it can also be adjusted upwards with an external resistor. The charge current can be set externally with a single resistor. When the input supply is removed, the CB06CRMA automatically enters a low power sleep mode , dropping the battery drain current to less than 3uA. Other features include undervoltage lockout, automatic recharge and charging indicator.

1-8Cell Nickel Metal Hydride Battery Charger
1-8Cell  NiCd Battery Charger
USB power protection:
When charging multiple batteries, the USB power supply needs to supply a large current. In order to ensure that no USB power is damaged, the NIUP11TA adds USB power protection. When the USB power supply voltage is pulled down to a certain threshold, reduce the charging current to protect the USB power supply. When the USB power supply voltage rises, adjust the charging current to the maximum value.
Short circuit protection and zero volt battery activation:
NIUP11TA can intelligently detect whether the output is short-circuited and indicate an error. The NIUP11TA allows long-term shorts in the output without damaging any circuitry and USB power, and the output is shorted and maintains low power consumption.
The NIUP11TA has a zero-volt battery activation function that determines a zero-volt battery when the short-circuit is detected for the first time after power-on. The horse activates the zero-volt battery, and the zero-volt battery activates and enters the normal charging process. If the zero volt battery is not activated, it will be judged to be a short circuit and the indicator light will start flashing.
 
Battery protection:
1) If the battery voltage is higher than 1.35V, the battery is considered to be close to full capacity. After plugging in, it will not be charged, and the indicator light will be extinguished to prevent the battery capacity from dropping due to the memory effect of the nickel-cadmium battery.
2) After the battery is connected, the number of battery packs will be judged. If the voltage is not within the corresponding range, charging will not be performed.
Charging process:
1) Battery insertion detection
When the charger is powered up, it will automatically detect the presence or absence of battery insertion. After detecting the zero-volt battery, it will be activated automatically. When the short-circuit is detected, an error will be indicated. If the number of battery packs is not matched with the circuit, an error will be reported. After the correct battery pack is inserted, normal charging will be performed.
 
2) Pre-charge
If the battery pack connected to the battery pack is less than 1V, it indicates that the battery is discharged too much. It needs to be activated after a small current is activated to prevent damage to the battery. Pre-charging requires a current of 100 mA and a fast charge when the single cell voltage is greater than 1V.
 
3) Fast charging
If the battery pack connected to the battery pack is already greater than 1V, it indicates that the battery has passed the precharge threshold and can be quickly charged. Fast charging requires current to be controlled at 250mA. The fast charging process should periodically detect the battery voltage and charging current, and detect the battery voltage -v or 0△V, and jump to make up the charging.
 
4) make up the charge
Fast charging has been used to charge the battery voltage to 1.3V or higher with a large current. If fast charging is used, the temperature of the battery will rise rapidly. It needs to be changed to a smaller current to make up the charge. At this time, the current is controlled at 200mA. Make up the charging time for 20 minutes, and then jump to trickle charging after the end of the charge.
5) trickle charging
In order to make up for the self-discharge of the battery, it will enter the trickle charge after the end of charging. The trickle charge current is 40mA. After entering the trickle charge, the indicator light has been extinguished. When the user removes the battery, it will enter the next charge cycle.
 
6) Battery take-out detection
When charging is entered, the system will continue to take the battery removal test. After detecting that the battery is removed, it will enter the next charging cycle.

LD06AJSA/B is a current regulation integrated circuit operating from an input voltage of 2.8V to 6V, the constant
output current can be set up to 1.5A with an external resistor. The LD06AJSA/B consists of high precision reference
voltage, amplifier, current mirror, etc. The on-chip power transistor and current sense block greatly reduce the
external component count, which makes the LD06AJSA/B ideal for LED driver.
When the CE pin is high, the input voltage is greater than 2.8V, and is larger than the LED forward voltage plus
the required voltage drop, LD06AJSA/B functions normally to deliver constant current from the LED pin.
The LD06AJSA/B adopts the temperature regulation instead of temperature protection function, the temperature
regulation can make the LED being turned on continuously in case of high ambient temperature or high voltage
drop. When the LD06AJSA/B junction temperature reaches about 135 ° C, the internal temperature regulation block
reduces the LED current so that the junction temperature will not rise any more. This feature allows the users to
maximize the use of the power handling capability of the chip, do not worry about the chip overheating and
damage to the chip or external components.
The LD06AJSA/B also has the chip enable function, which can shutdown the whole chip to limit the current
consumption within 1uA.
The LD06AJSA/B also adopts the over current protection block. When LED current approaches 1.9A(Typical), the
over current protection block begins to function to prevent the LED current from increasing further.
