EG4328 from EG Micro, in a SOP-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 | VREF | power_out | 2.5V reference (±1%, 2.475-2.525V at VCC=5V, max 1mA output) with an external 0.1uF capacitor, used as the internal ADC reference. |
| 2 | AD0 | input | ADC input channel 0 of the 8-channel 10-bit ADC. |
| 3 | AD5 | input | ADC input channel 5 of the 8-channel 10-bit ADC. |
| 4 | VFB1 | input | Voltage feedback input 1, with a configurable voltage-loop reference of 1.05V to 1.425V. |
| 5 | IAPO | output | Current signal amplifier output, with an external 0.1uF capacitor. |
| 6 | IFB | input | Current feedback input, with a configurable internal reference of 1mV to 112mV. |
| 7 | SCL | bidirectional | I2C clock line (slave mode, up to 100kbps); a falling edge wakes the chip from sleep. |
| 8 | SDA | bidirectional | I2C data line (slave mode, write address 0xB4, read address 0xB5). |
| 9 | VFB2 | input | Voltage feedback input 2, with a configurable reference of 1.05V to 1.272V. |
| 10 | VOUT | output | Voltage and current error amplifier output (VOL max 0.5V at 5mA sink). |
| 11 | GND | power_in | Chip ground. |
| 12 | VCC | power_in | Chip supply pin, 2.5V to 5.5V operating (absolute maximum 6V). |
| 13 | LED4 | output | Battery level indicator LED4 output with adjustable constant current (0.4mA to 5.88mA). |
| 14 | LED3 | output | Battery level indicator LED3 output with adjustable constant current (0.4mA to 5.88mA). |
| 15 | LED2 | output | Battery level indicator LED2 output with adjustable constant current (0.4mA to 5.88mA). |
| 16 | LED1 | output | Battery level indicator LED1 output with adjustable constant current (0.4mA to 5.88mA). |
