FH2112CB

XIN FEI HONG · Battery Management ICs · SOT-23-6

FH2112CB from XIN FEI HONG, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OD output Gate connection for the discharge control MOSFET; driven low on overdischarge, discharge overcurrent or load short (output high VDD-0.02V typ, low 0.1-0.5V).
2 CS input Overcurrent detection input and charger detection pin; high-voltage design with absolute maximum range VDD-20V to VDD+0.3V.
3 OC output Gate connection for the charge control MOSFET; driven low on overcharge or charge overcurrent, absolute maximum range VDD-20V to VDD+0.3V.
4 NC unconnected No connection.
5 VDD power_in Positive power supply input; operating voltage VDD-VSS 1.5V to 8V, absolute maximum VSS+10V.
6 VSS power_in Ground, negative power supply input (0V reference).
