FH9261-G3JH

鑫飞宏 · Battery Management · SOT-23-6

FH9261-G3JH from 鑫飞宏, 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 DO output Drives the discharge-control MOSFET and goes low to turn it off on over-discharge (VOD 3.000 V), discharge overcurrent (VEC 0.080 V) or load short circuit (VSHORT 1.000 V); DO voltage is rated VSS-0.3 V to VDD+0.3 V.
2 VM input Current-sense input used for charge and discharge overcurrent, short-circuit and charger detection, rated VDD-12 V to VDD+0.3 V.
3 CO output Drives the charge-control MOSFET and goes low to turn it off on over-charge (VOC 4.280 V) or charge overcurrent (VCHA -0.100 V); CO voltage is rated VVM-0.3 V to VDD+0.3 V.
4 NC unconnected Listed as NC in Table 1; the datasheet gives no function or connection requirement for this pin.
5 VDD power_in Positive supply input for the IC, with chip supply voltage of 1.0 V to 7.5 V and an absolute maximum of VSS-0.3 V to VSS+8.0 V between VDD and VSS.
6 VSS power_in Ground reference for the IC; the battery voltage is measured between VDD and VSS and VM is referenced to VSS.
