BRCL3130BME 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 or tie as convenient on the PCB.
2	GND	power_in	Ground reference. Connect the negative terminal of the battery to this pin.
3	VDD	power_in	Power supply input, typically connected to the battery positive terminal through a 100 Ω series resistor with a 0.1 µF decoupling capacitor to GND. Absolute maximum VIN range is -0.3 V to +6.0 V.
4	VM	power_out	Charger negative sense / internal FET switch node. The internal power MOSFET (~40 mΩ) connects this pin to GND to allow charge/discharge current. Absolute maximum VVM range is -4.0 V to +8 V.
5	VM	power_out	Charger negative sense / internal FET switch node (same net as pin 4). The internal power MOSFET connects this pin to GND during normal operation. Absolute maximum VVM range is -4.0 V to +8 V.
