Pinout
The XB3303A is a 6-pin battery protection IC designed for overcharge, over-discharge, and overcurrent protection in single-cell lithium-ion/polymer batteries.
Pin Functions:
1. VDD – Power supply input (connects to battery positive).
2. VSS – Ground (connects to battery negative).
3. CO – Charge control output (drives charge MOSFET gate).
4. DO – Discharge control output (drives discharge MOSFET gate).
5. VM – Detects charge/discharge current (connects between MOSFETs).
6. NC – No connection (unused pin).
It ensures safe battery operation by cutting off power during faults.
