As VRLA battery charge special chip, UC3906 has 3 kinds of charging logic control and detection function to achieve the best charge of VRLA battery, it also has the functions of environmental temperature self-adapting, charge-discharge extent self-adapting, and current limiting, under-voltage protection. The adopted temperature compensation technology can make all kinds of charging transformational voltage change in relation to the VRLA battery voltage temperature coefficient, then the VRLA battery will reach the best charging state within a wide temperature range. The internal structure diagram is shown as below:

The circuit mainly includes power supply, trigger start and control, to control load R1 turn on or off power supply through TRIAC ZN6346. Once the AC power voltage is too high, the ○A point's voltage on constant current component 1N5314 is rising, then the unidirectional SCR 2N5O6O turns on and transistor MPS6581 turns off, SCR 2N6239 turns off too, finally, main bi-directional SCR turns off, it can protect load from overvoltage damaging.
