Figure19 Anti-reverse-insertion circuit

4 .Second-time power voltage-limiting module

The second-time power voltage-limiting module limits the second-time power voltage to 4.4V.

When the constant current charging operation is ended, the second-time power output is stabilized to

4.4V to provide power for the back-level circuit.. The feedback loop is accomplished by operational

amplifier 1 of TL494.
