# BRCL3130ME-A

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

BRCL3130ME-A from Foshan Blue Rocket Elec, in a SOT-23-5. 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 | NC | unconnected | No electrical connection. Leave floating. |
| 2 | GND | power_in | Ground reference for the IC. Connects to the negative terminal of the battery cell. |
| 3 | VDD | power_in | Power supply input, taken from the positive terminal of the Li-ion/Li-poly cell through a 100Ω series resistor and a 0.1µF decoupling capacitor to GND. Absolute max VIN = -0.3 to +6.0V. |
| 4 | VM | power_out | Negative terminal of the charger / pack minus. The internal charge/discharge FET switch connects this pin to GND during normal operation. Also used to sense charger presence, overcurrent and load short-circuit conditions. Absolute max VVM = -6.0 to +10V. |
| 5 | VM | power_out | Negative terminal of the charger / pack minus (second VM pad). Internally connected to pin 4; both pins carry the FET switch node to GND. |
