TP4066 from HXY MOSFET, 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 | TEMP | input | Battery temperature sense input compared against 45% and 80% of VCC thresholds; connect to GND to disable temperature monitoring. |
| 2 | PROG | passive | Constant-charge current set and charge current monitor pin; a resistor RPROG to GND programs the current (1.1k gives 1000mA) with a 1.0V typical PROG voltage. |
| 3 | GND | power_in | Ground. |
| 4 | VCC | power_in | Positive input supply, operating range 4.2V to 9V (absolute maximum 9V). |
| 5 | BAT | power_out | Battery connection pin supplying charge current, with float voltage of 4.2V or 4.35V and battery reverse-connection protection. |
| 6 | STDBY | output | Open-drain charge-complete indicator output, pulled low when charging has terminated. |
| 7 | CHRG | output | Open-drain charge status indicator output, pulled low while charging. |
| 8 | CE | input | Chip enable input; high enables charging and low stops charging. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
