SHOUDING · Battery Management · SOT-23-5

SD5054 from SHOUDING, in a SOT-23-5. 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 CHRG output Open-drain charge status indicator. Pulled low through an internal N-channel MOSFET while charging is in progress; goes to a high-impedance state when the charge cycle completes or the device enters UVLO. VCHRG(low) = 0.35V typ (0.6V max) at ICHRG = 5mA.
2 GND power_in Power ground / device reference.
3 BAT power_out Battery connection. Sources charge current to the single-cell Li-Ion battery and regulates the final float voltage to 4.2V (±1%) via an internal precision resistor divider. Disconnected in shutdown; battery drain current falls below 2µA when input power is removed.
4 VCC power_in Charger supply input; operating range 4.25V to 6.5V (absolute max 7V). Bypass with at least 1µF to GND. When VCC − VBAT < ~30mV the part enters shutdown and IBAT drops below 2µA.
5 PROG bidirectional Charge-current program, monitor, and shutdown pin. A 1% resistor RPROG from PROG to GND sets the constant-current level: IBAT = (VPROG/RPROG)·1000 (VPROG = 1V in CC mode, 0.1V in precharge). Floating the pin lets an internal 3µA pull-up bring PROG above the 1.21V shutdown threshold, putting the charger in shutdown with ICC ≈ 25µA. Pin is internally clamped near 2.4V.
