SGM4056-6.8YPS8G from SGMICRO, in a SOIC-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 | VIN | power_in | Power input with an absolute maximum input voltage of 26.5V; a 1µF or larger X5R ceramic capacitor is recommended very close to the pin for decoupling. |
| 2 | PPR | output | Open-drain power presence indication that turns on when the input is above the POR threshold but below the OVP threshold, can sink at least 15mA, and has a maximum voltage rating of 5.5V. |
| 3 | CHG | output | Open-drain charge indication that outputs logic low when a charge cycle starts, goes high impedance at end-of-charge, can sink at least 15mA, and is high impedance when the charger is disabled. |
| 4 | EN | input | Logic enable input where driving high disables the charger and driving low or leaving it floating enables it, with an internal 200kΩ pull-down resistor. |
| 5 | GND | power_in | System ground. |
| 6 | IMIN | passive | End-of-charge current programming pin; a resistor to GND sets the EOC current, which should be programmed within 5% (or 10mA, whichever is higher) to 50% of IREF, with stability not guaranteed below that range. |
| 7 | IREF | passive | Charge-current programming and monitoring pin; a resistor to GND sets the charge current limit, should be placed very close to the pin, and the pin voltage tracks actual charge current (0V when disabled). |
| 8 | BAT | power_out | Charger output connected to the battery, requiring a 1µF or larger X5R ceramic capacitor for decoupling and stability; the BAT output is disabled when EN is driven high. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
