FH7071B

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

FH7071B 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 connected to gate of external discharge control N-MOS transistor Q2.
2 VM input Charge/discharge current detection input, connected through 1kΩ resistor to source of N-MOS transistor Q1, detects voltage drop across charge/discharge MOSFETs.
3 COUT output Charge control output connected to gate of external charge control N-MOS transistor Q1.
4 NC unconnected Not connected (floating pin).
5 VDD power_in Power supply input connected to positive terminal of battery, requires 0.1μF ceramic capacitor decoupling, operating voltage range -0.3V to +10V.
6 VSS power_in Power supply ground connected to negative terminal of battery.
