TP4586 from TPOWER, in a QFN3x3-16. 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 | VDD | power_in | Charging input supply, recommended 4.5 V to 5.5 V with absolute maximum -0.3 V to +28 V and an input overvoltage protection threshold of 6.7 V. |
| 2 | SWT | input | Button input with about 30 µA internal pull-up; in EN=L and COM=L mode a single click (over 50 ms) turns on, and a double click within 500 ms turns off, the VOL/VOR outputs, and it is ignored when EN=L and COM=H. |
| 3 | LED1 | output | Indicator LED driver: battery-level LED in 4-LED mode and charge-status LED in 2-LED mode, with a typical drive current of 1.4 mA. |
| 4 | LED2 | output | Indicator LED driver: battery-level LED in 4-LED mode and discharge-status LED in 2-LED mode, with a typical drive current of 1.4 mA. |
| 5 | LED3 | output | Indicator LED driver for battery level in 4-LED mode; in 2-LED mode this pin must be shorted to GND. |
| 6 | NTC | input | Battery temperature sense input; connect the NTC thermistor to GND, and tie this pin to GND when the NTC function is not used. |
| 7 | VB | power_out | Bias voltage output for the NTC divider network, connected through a resistor to the NTC pin, and left floating when the NTC function is not used. |
| 8 | COM | input | VOR/VOL output-state control pin used together with EN; logic high threshold is 1.5 V and logic low threshold is 0.3 V, and it must be tied to GND when unused. |
| 9 | EN | input | Chip enable and VOR/VOL output-state control pin; the boost output is off above 1.5 V and enabled below 0.3 V, and it must be tied to GND when unused to enter automatic load detection. |
| 10 | PROG | passive | Charge-current setting pin with a resistor to GND; the datasheet gives 2 kΩ for 450 mA to 550 mA charge current at IBAT, and the maximum charge current is 500 mA. |
| 11 | IEND | passive | Light-load auto-shutoff current setting pin with a resistor to GND, where REND (kΩ) = 250 / IEND (mA); 49.9 kΩ gives 5 mA typical shutoff current. |
| 12 | BAT | bidirectional | Lithium-ion battery positive terminal, charged to a float voltage of 4.15 V to 4.25 V (4.2 V typical) and used as the boost input during discharge. |
| 13 | SW | output | Boost power switch node, which should be kept short and wide to the inductor L1 as stated in the layout guidance. |
| 14 | VOL | output | Left earphone charging/discharge output with a 250 mA overcurrent threshold and a 2.0 V short-circuit detection threshold. |
| 15 | VOR | output | Right earphone charging/discharge output with a 250 mA overcurrent threshold and a 2.0 V short-circuit detection threshold. |
| 16 | OUT | power_out | Synchronous boost output, 5.05 V typical at 0.5 A with an overvoltage protection threshold of 5.30 V. |
| 17 | GND | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
