ETA4056E8A from etasolution, in a ESOP8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NTC | input | Battery temperature monitoring input pin for setting valid temperature operating range for charging and discharging. |
| 2 | ISET | bidirectional | Program and monitor charge current via 1% resistor to GND; IC maintains 1V in constant-current mode; disconnect resistor to disable charger. |
| 3 | GND | power_in | Ground reference. |
| 4 | VIN | power_in | Positive input supply; requires bypass with at least 4.7μF capacitor; 16V input standoff voltage. |
| 5 | BAT | output | Charge current output; provides current to battery and regulates float voltage to 4.2V with ±1% accuracy. |
| 6 | STDBY | output | Open-drain output for charge finished flag; low when charging complete, high-impedance during charging. |
| 7 | STAT | output | Open-drain output for in-charging flag; low during charging, high-impedance upon charge cycle completion. |
| 8 | EN | input | Enable/disable charger; drive high or floating to enable, low to disable. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
