BRCL4054DME

Foshan Blue Rocket Elec · Battery Management ICs · SOT-23-5

BRCL4054DME from Foshan Blue Rocket Elec, in a SOT-23-5. 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 CHRG output Open-drain charge status indicator that outputs logic low while charging and high impedance when the charge cycle is terminated (absolute max -0.3 to 8 V).
2 GND power_in Chip ground.
3 BAT bidirectional Battery connection that sources charge current and regulates to a 4.20V float voltage (±1%), with a drain current below 3µA in sleep mode (absolute max -0.3 to 7 V).
4 VDD power_in External DC 5V input supply with a 4 to 6 V operating range (absolute max -0.3 to 8 V).
5 PROG passive Charge current programming pin where a resistor to ground sets the charge current (absolute max -0.3 to 8 V).
