BRCL4056BSE 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 | TEMP | input | External temperature sensing pin; the datasheet uses TEMP for battery temperature fault detection and for the no-battery indication (TEMP=GND). |
| 2 | PROG | passive | Charge current regulator pin; a single resistor from PROG to GND sets the constant charge current, with PROG at 1.0V in high-current mode and 0.1V in trickle mode per the electrical characteristics. |
| 3 | GND | power_in | Chip ground. |
| 4 | VDD | power_in | External DC 5V input; the operating input voltage range is 4V to 6V, with undervoltage lockout threshold of 3.7V (200mV hysteresis). |
| 5 | BAT | power_out | Battery connection pin that supplies the charge current to the cell; it regulates to a preset 4.20V float voltage with ±1% accuracy and the charger enters trickle charge below 2.8V. |
| 6 | STDBY | output | Open-drain battery charge-complete indicator; it is pulled low when the charge cycle terminates at 10% of the programmed charge current. |
| 7 | CHRG | output | Open-drain charging indicator; it is pulled low while a charge cycle is in progress and goes high-impedance when charging terminates. |
| 8 | NC | unconnected | Vacant pin, not connected. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
