LP28300ASPF from LOWPOWER, 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 | SW | power_out | Switch pin that connects to the external inductor. |
| 2 | BST | passive | Internal charge pump boost pin. |
| 3 | STAT | output | Open-drain charge status output that an internal N-channel MOSFET pulls low while the battery is charging, and that goes high impedance on an under-voltage lockout condition. |
| 4 | NTC | input | NTC thermistor input that senses battery pack temperature and stops charging when out of range; connect to GND to disable this function (pulling it to VIN shuts the charger down). |
| 5 | BAT | bidirectional | Battery pin. |
| 6 | RS | input | Charge current detecting pin, sensed across the RSNS resistor to BAT with a 50mV reference. |
| 7 | REG | input | Input voltage feedback for the input voltage regulation loop; connect to the tap of a resistor divider from VIN to GND, and charge current is reduced once REG drops to the 1V internal threshold. |
| 8 | VIN | power_in | Positive supply voltage input (4V to 18V operating range), decoupled with a 10µF or larger surface mount ceramic capacitor. |
| 9 | GND | power_in | Ground, provided through the exposed pad, which must be connected to the ground plane for proper power dissipation. |
