IP5407 from INJOINIC, 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 | VIN | power_in | DC 5V charging input pin; recommended input voltage 4.65V to 6V, absolute maximum -0.3 to 6V. |
| 2 | DCP | bidirectional | Connects to USB-A D+/D- for automatic phone charging-current identification (DCP), default D+=D-=2.7V. |
| 3 | KEY | bidirectional | Multiplexed pin for key input, lighting LED drive and NTC detection; tie a 51K resistor to GND if NTC is not used. |
| 4 | LED1 | output | LED drive pin for battery level display, drive current 5 mA. |
| 5 | LED2 | output | LED drive pin for battery level display, drive current 5 mA. |
| 6 | BAT | power_in | Boost input pin connected to the lithium battery positive terminal; battery operating voltage 3V to 4.4V. |
| 7 | SW | passive | DC-DC switching pin connected to the inductor (1.0uH recommended). |
| 8 | VOUT | power_out | 5V boost output pin, up to 2.1A load capability. |
| 9 | GND | power_in | Exposed power PAD, connect to GND. |
