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.

You can select different modes of operation with"M4 M3 M2 M1 M0" pad in the delay mode to adjust the delay time through an adjustable resistor.
In delay mode, the rotary variable resistor can adjust the delay time. Increase the time counterclockwise rotation, and clockwise rotation to shorten the time. Adjustable resistor is a precision resistor, adjust the time with a Phillips screwdriver to gently rotate (do not use excessive force)
Working Mode Description:
Non-locking: Press the remote control button, the IO port outputs high. Release the remote control button, IO port outputs low.
Self-locking: Press the remote control button, the IO port outputs high. Press the remote control button again, IO port outputs low.
Interlock: Press the remote control button D0, D0 IO port outputs high, other IO ports outputs low; remote control button is pressed D1, D1 IO port outputs high, other IO ports output low and so on.
Delay: Under Delay mode, there is a delay 0/1/2/3/4 five sub-patterns, by adjusting the variable resistor IO port high duration

In normal operation mode, LED (D1) will be lit, when receiving a valid remote control (EV1527 / PT2262) key value, LED will flash.
Clean code: hold the button to press.LED offs, keep pressing about 8 seconds until LED lights. At that time, clean code completion (Note: After the implementation of clean code, previous remote controls do not exist.
Adaptation (learning):
Step 1 (into the learning mode):trigger the key button, LED offs;
Step 2 (adapter channel 1): press the first button of remote control and then, LED offs after flashes for four times. This time means that it had learned the value of the first button
Step 3 (Adaptation Channel 2): Press the second remote control, LED offs after flashes 4 times, This time means that it had learned the value of the second button
Step 4 (adapter Channel 3): Then press the remote's third button, LED offs after flashes 4 times, This time means that it had learned the value of the third button
Step 5 (Adaptation Channel 4): Then press the remote control's fourth button, LED lights after flashes 4 times, This time means that it had learned the value of the fourth button.

PCB Size:41×20×15mm;
Max load : 500W;
 
Advantage :
1: Receiver Mother board have a learning key , if the remote is lost , must buy EV1527 OR Pt2262 remotes to re-learn;
 
Relay mode :
Normally close (NC ) ;
Normally open (NO ) ;
Normally-open (NO) contacts connect the circuit when the relay is activated; the circuit is disconnected when the relay is inactive. It is also called a Form A contact or "make" contact. NO contacts may also be distinguished as "early-make" or NOEM, which means that the contacts close before the button or switch is fully engaged.
Normally-closed (NC) contacts disconnect the circuit when the relay is activated; the circuit is connected when the relay is inactive. It is also called a Form B contact or "break" contact. NC contacts may also be distinguished as "late-break" or NCLB, which means that the contacts stay closed until the button or switch is fully disengaged.
   
Learning method and steps:
1 Press the learning button and LED on the receiver will light up, enter the learning state.
 
2 Press the key you want to learn on remote control within 2-5 seconds , LED flash 3 times and then turn off , then it have success in learning .
 
  
Clear the deposit information
Keep Pressing Learning Key , LED turns on , Wait 8-10 Seconds , LED turn off , that deposited information has been successfully cleared ;
 
Work mode (programmable ):
singnal Non-locking (Momentary    is defult )
singnal Self-locking (Toggle  )
singnal Inter-locking (Latch)
Work Mode can be adjustable by jumper,Please operation under power off
 
Work mode explanation:

Status : Working State, Power-Saving Status, Setting State
Working State: In working state when powered on, F00-F05 mode displays remaining time, F10-F15 mode displays remaining time and pulse count value.
Note: When the remaining time is higher than four digits, short press the ''OK'' button to scroll to display the remaining time once.
Setting Status: Short press the ''SET'' button to enter the Setting Status, then short press ''SET'' to switch parameters, short press '' ''/''--'' to modify parameters. Short press the ''OK'' button to save the parameters and exit the setting state.
Note: After setting the parameters, it must be powered on again.
 
Query Status: without modifying the parameter Setting Status, short press the ''SET'' button to enter the Query Status, then press ''SET'' to switch parameters, and short press the ''OK'' button to exit the Query Status
Power-Saving Status: The Working State of the digital tube is turned off. In this state, the digital tube does not display and other functions work normally. Press and hold the ''OK'' button for 5 seconds to enter the Power-Saving Status, and press and hold the ''OK'' button again for 5 seconds to exit the Power-Saving Status.
Notice:
1 In the Power-Saving Status, you can still enter the setting and query state, and it will automatically enter the Power-Saving Status state after 20 seconds of no key operation.
2 After the power is turned on again, the Digital Tube displays for 20 seconds, how to turn off the Digital Tube.
Factory Setting: Press and hold the '' '' and ''--'' buttons simultaneously for 3 seconds to restore the Factory Settings and turn off the display of the digital tube. Run the default parameters after power cycle.
Note: After setting the parameters, it must be powered on again.
Exception handling:
1 If you encounter inexplicable problems, please power on again (this is because there is no restart after setting parameters)
2 If the problem still cannot be solved after powering on again, please press and hold the '' '' and ''--'' buttons simultaneously for 3 seconds to restore the factory settings. then power on again
