BRCL4058ESE

Foshan Blue Rocket Elec · Battery Management · ESOP-8

BRCL4058ESE from Foshan Blue Rocket Elec, in a ESOP-8. 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 TS input External NTC temperature-sense input; charging is paused when VTS falls outside the 45%×VDD to 80%×VDD window, and tying TS to GND disables battery temperature detection.
2 PROG passive Charge-current program pin; a 1% resistor to GND sets the charge current via RPROG(kΩ)=1180/IBAT(mA), with charge current up to 1.2 A.
3 GND power_in Chip ground.
4 VDD power_in Input supply from USB or AC adapter, 4.5 V to 6.0 V operating range; absolute maximum -0.3 V to 30 V, with input over-voltage protection at 6.9 V typical.
5 BAT power_out Charger output to the single-cell Li-ion battery, regulated to 4.2 V float voltage (4.158 V to 4.242 V); absolute maximum -0.3 V to 20 V.
6 STDBY output Open-drain full-charge indicator output, high impedance while charging and pulled low when the battery is full; absolute maximum -0.3 V to 30 V.
7 CHRG output Open-drain charge-in-progress indicator output, pulled low while charging; absolute maximum -0.3 V to 30 V.
8 CE input Charge enable input where high level (1.5 V to 5 V) shuts the charger down and low level (0.2 V max) enables operation; absolute maximum -0.3 V to 6 V, leave floating if unused.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
