PJP1103ASE from PJSEMI, 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 connection. Leave floating or tie per PCB requirements. |
| 2 | GND | power_in | Ground / negative supply reference. Connect to the negative terminal of the battery. |
| 3 | VDD | power_in | Positive supply input. Connect to the battery positive terminal, typically through a series 1 kΩ resistor with a 0.1 µF bypass capacitor to GND. Absolute max VDD-GND = -0.3 V to +6 V; typical operating current ~1.0 µA at VDD=3.6 V. |
| 4 | VM | bidirectional | Charge/discharge current sense terminal. Connects internally through the on-chip power MOSFET (RDS(on) ~70 mΩ) to GND; the external node ties to the charger/load negative terminal (P-). Sensed voltage across VM-GND is used to detect discharge overcurrent (2 A), short-circuit (4 A), and charge overcurrent (2 A). Absolute max VVM = -6 V to +10 V. |
| 5 | VM | bidirectional | Charge/discharge current sense terminal (second VM pin, tied internally to pin 4). Connects to the charger/load negative terminal (P-) through the internal power MOSFET path to GND. Used together with pin 4 to carry the pack current. |
