This type of PCBA is consist of featured as,
1-complete switch over system with Relays etc, to maintain power failure and power restore.which is essential for UPS.
2-oscillator output to drive half bridge FETs.
3-cut off charging when battery reaches its max volts(14.4 volts).
4-during UPS mode low bat warning and switch off.
5-overload protection,during UPS mode.to protect FETs.
6-battery condition monitor with 5 LEDs,during charging mode these 5 LEDs blink same as you can see in nokia cell phon screen.when we charge nokia cell phone.
if you need only PIC16F72 or complete PCBA.
