Pinout
11Low source legibility.The original manufacturer datasheet for this part was difficult to read, so this pinout may be incomplete or imperfect. Always confirm against the specific manufacturer’s datasheet before wiring.
| Pin | Name | Functions | Notes |
|---|---|---|---|
| VBUS | 5V Power Rail | POWER | The power rail from the USB connector and DC barrel jack. |
| OUT | Load Output | POWERGND | Regulated output when input voltage is below over-voltage protection threshold, up to 4.4V. |
| LIPO | Battery Input | POWERGND | Connects to the positive terminal of a LiPo/LiIon battery. |
| GND | Common Ground | GND | Ground for all power and logic. |
| D+/D- | USB Data Lines | GPIO | Data lines from the USB socket, can be used to connect to other components. |
| EN1 and EN2 | Input Current Limit Configuration | GPIO | Configures input current limit; default is 500mA with an external resistor, can be adjusted. |
| CE | Charge Enable (Active Low) | GPIO | Disables charging when pulled high. |
| THERM | NTC Thermistor Input | GPIO | Optional input for temperature monitoring of the battery pack. |
| ISET | Fast Charge Current Setting Input | GPIO | Manually sets charge current if not using jumpers; can be left unconnected. |
| PGOOD | Power Good Status (Active Low) | GPIO | Indicates valid input source, active low. |
| CHG | Charge Status (Active Low) | GPIO | Indicates battery is charging, active low. |
