BRCL4056SE from Foshan Blue Rocket Elec, 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 | TEMP | input | Battery temperature sense input. Connect to the output of an NTC thermistor on the battery pack. Charging is paused if V(TEMP) < 45%·VCC or > 80%·VCC (battery too hot/cold), and resumes when the voltage returns inside that window. Tie to GND to disable the temperature-monitoring function. |
| 2 | PROG | passive | Charge-current program and monitor pin. A resistor R_PROG from PROG to GND sets the charge current: precharge clamps V(PROG) to 0.1V and constant-current mode regulates V(PROG) to 1.0V, so I_BAT = (V_PROG / R_PROG) × 1000. The pin voltage can also be read to monitor instantaneous charge current in all charge states. |
| 3 | GND | power_in | Device ground / power return. |
| 4 | VCC | power_in | Positive supply input, 4.5V-6.5V operating range (absolute max 10V). Powers the internal circuitry and the pass FET to the battery. When (VCC − V_BAT) falls below ~80mV, the part enters low-power sleep mode and BAT sink current drops below 2µA. |
| 5 | BAT | power_out | Battery connection / charge output. Sources charge current to the single-cell Li+ pack and regulates it to 4.2V float. Draws less than 2µA from the battery when the part is disabled or in sleep mode. |
| 6 | STDBY | output | Open-drain charge-complete (standby) indicator. Internal switch pulls low when charging has terminated (battery full); otherwise the pin is high-impedance. Absolute max sink current 10mA - typically drives an LED to VCC through a series resistor. |
| 7 | CHRG | output | Open-drain charging-in-progress indicator. Internal switch pulls low while the charger is actively delivering current to the battery; otherwise the pin is high-impedance. Absolute max sink current 10mA - typically drives an LED to VCC through a series resistor. |
| 8 | CE | input | Chip-enable input. Logic high enables normal charging operation; logic low forces the device into charge-disabled state. Compatible with TTL and CMOS logic levels (V_IH ≥ 1.5V, V_IL ≤ 0.4V). |
| 9 | EPAD | power_in | Exposed thermal pad on the package bottom. Must be soldered to a PCB ground copper plane to achieve the specified thermal performance and to provide electrical ground contact. |
