FH9261-DAI

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

FH9261-DAI from XIN FEI HONG, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OD output Discharge control MOSFET gate drive. Drives the gate of the discharge N-MOSFET; output high (VDD-0.02V typ) enables discharge, output low (0.1V typ) disables discharge when overdischarge or discharge overcurrent is detected.
2 CS input Overcurrent detection input / charger detection terminal. Senses voltage across the series MOSFETs to detect discharge overcurrent (VDIP=180mV), charge overcurrent (VCIP=-150mV) and load short-circuit (VSIP=0.58V typ). Absolute max VDD-25V to VDD+0.3V (25V high-withstand-voltage design for charger connection).
3 OC output Charge control MOSFET gate drive. Drives the gate of the charge N-MOSFET; output high (VDD-0.02V typ) enables charging, output low (0.1V typ) disables charging when overcharge or charge overcurrent is detected. Absolute max VDD-25V to VDD+0.3V (25V high-withstand-voltage design).
4 NC unconnected No connection. Leave floating.
5 VDD power_in Positive power supply input. Connect to battery positive via a 100Ω series resistor and 0.1µF decoupling cap to VSS. Operating voltage 1.5V to 8V (absolute max VSS-0.3V to VSS+10V). Typical operating current 3.0µA at VDD=3.9V.
6 VSS power_in Ground / negative power supply input. Connect to battery negative.
