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). |
