LP4056HSPF

LOWPOWER · Battery Management · ESOP-8

LP4056HSPF from LOWPOWER, in a ESOP-8. 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 NC unconnected No connect. Leave floating.
2 ISET passive Charge current program and monitor pin. A 1% resistor RISET from ISET to ground programs the charge current per IBAT = 1000V/RISET. Servos to 1.0V in constant-current mode; ISET voltage may be read to monitor charge current.
3 VSS power_in Device ground / system ground return.
4 VIN power_in Input power supply, 4.5V to 6.5V (typ. 5V, absolute max 8V). Connect to wall adapter or USB source; decouple with 10uF ceramic.
5 BAT power_out Charger output to the single-cell Li-Ion battery. Regulated float voltage 4.2V ±1%; delivers up to 1000mA (RISET = 1k). Decouple with 10uF ceramic.
6 STAT2 output Open-drain charge status output (complement of STAT1). Pulled HIGH via external pull-up while charging, pulled LOW by internal N-MOSFET when the charge cycle completes.
7 STAT1 output Open-drain charge status output. Pulled LOW by internal N-MOSFET while charging, released HIGH via external pull-up when the charge cycle completes.
8 EN input Chip enable. Charging is enabled when EN is floating or pulled high (VIH >= 1.4V). Pulling EN low (VIL <= 0.4V) disables charging (shutdown).
9 GND power_in Exposed thermal pad on ESOP-8 bottom. Solder to a large PCB ground plane for heat dissipation; electrically tied to GND/VSS.
