FH9261-DAO

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

FH9261-DAO 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 DOUT output Discharge control output. Connects to the gate of the external discharge control N-MOSFET (Q2). Drives high (VDD) in normal state to turn Q2 on; drives low (VSS) to disconnect the discharge path when over-discharge, over-current or short-circuit protection is triggered.
2 VM input Charge/discharge current sense input. Connected through a current-limit resistor (typically 1kΩ) to the source of the external charge control N-MOSFET (Q1) to sense the voltage drop across Q1 and Q2. Also used for charger detection (VCHG ≈ -0.5V) and short-circuit detection (VSHORT ≈ 1.36V).
3 COUT output Charge control output. Connects to the gate of the external charge control N-MOSFET (Q1). Drives high (VDD) in normal state to turn Q1 on; drives low (VM level) when overcharge protection is triggered to block the charging path.
4 NC unconnected No connection. Leave floating (悬空).
5 VDD power_in Positive power supply input. Connects to the battery positive terminal through a series resistor R1 (typ. 330Ω); decouple with a 0.1μF ceramic capacitor to VSS. Operating range 1.5V to 10V; absolute max 10V.
6 VSS power_in Ground / negative power supply input. Connects to the battery negative terminal. All internal voltage thresholds are referenced to VSS.
