TP4366E from TPOWER, in a ESOP-8-EP. 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 | OUT | power_out | Boost output positive terminal and output voltage sense pin (5V/1A output, 4.8V to 5.2V at 1A load with VBAT=3.7V). |
| 2 | BAT | power_in | Lithium-ion battery positive terminal; charges at 0.8A constant current (100mA trickle below 2.9V) and discharge stops at 2.85V. |
| 3 | SW | passive | Drain of the boost power NMOS, connected to the inductor (inductor saturation current must exceed 3A). |
| 4 | GND | power_in | Chip ground. |
| 5 | SWT | bidirectional | Connects to the push button and flashlight LED: short press shows battery level, 2s long press toggles the flashlight, with a maximum drive current of 50mA. |
| 6 | VDD | power_in | Power (charge) input, recommended 4.5V to 5.5V with 6.5V overvoltage protection and recovery below 5.8V. |
| 7 | LED2 | output | LED drive pin for charge state and battery level indication, 2mA drive current at BAT=4V. |
| 8 | LED1 | output | LED drive pin for charge state and battery level indication, 2mA drive current at BAT=4V, flashes at 2Hz for low battery alarm. |
| 9 | GND | power_in | Exposed pad heat sink connected to chip ground; must be well soldered to the PCB ground. |
