EG2125 from EG Micro, in a SSOP-24. 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 | HIN1 | input | Channel 1 high-side logic input, active high, turns the high-side MOSFET on (HO1 high) when set to 1 and off when set to 0, with an internal 250 kΩ pull-down so the output is off when the input floats. |
| 2 | SD1 | bidirectional | Active-low shutdown for channel 1 that forces LO1 and HO1 low regardless of HIN1 and LIN1; the datasheet lists this pin as I/O. |
| 3 | LIN1 | input | Channel 1 low-side logic input, active high, turns the low-side MOSFET on (LO1 high) when set to 1 and off when set to 0, with an internal 250 kΩ pull-down. |
| 4 | CINN1 | input | Negative input of comparator 1 (over-current detection). |
| 5 | CINP1 | input | Positive input of comparator 1 (over-current detection); comparator input range is 0.1 V to VCC. |
| 6 | LO1 | output | Channel 1 low-side gate driver output for the low-side power MOSFET, rated for 0.8 A source and 1.3 A sink peak (pulse width ≤10 µs). |
| 7 | VCC | power_in | Supply input for the chip, 10 V to 20 V, which should be decoupled with a high-frequency bypass capacitor close to the pin. |
| 8 | NC | unconnected | No connection; leave floating. |
| 9 | NC | unconnected | No connection; leave floating. |
| 10 | VS2 | power_in | Floating high-side ground reference for channel 2 (high-side source node). |
| 11 | HO2 | output | Channel 2 high-side gate driver output for the high-side power MOSFET, rated for 0.8 A source and 1.3 A sink peak (pulse width ≤10 µs). |
| 12 | VB2 | power_in | Floating high-side bootstrap supply for channel 2, referenced to VS2. |
| 13 | HIN2 | input | Channel 2 high-side logic input, active high, turns the high-side MOSFET on (HO2 high) when set to 1 and off when set to 0, with an internal 250 kΩ pull-down. |
| 14 | SD2 | bidirectional | Active-low shutdown for channel 2 that forces LO2 and HO2 low regardless of HIN2 and LIN2; the datasheet lists this pin as I/O. |
| 15 | LIN2 | input | Channel 2 low-side logic input, active high, turns the low-side MOSFET on (LO2 high) when set to 1 and off when set to 0, with an internal 250 kΩ pull-down. |
| 16 | CINN2 | input | Negative input of comparator 2 (over-current detection). |
| 17 | CINP2 | input | Positive input of comparator 2 (over-current detection); comparator input range is 0.1 V to VCC. |
| 18 | GND | power_in | Low-side ground reference for the chip; the datasheet requires it to be common with the MCU ground. |
| 19 | LO2 | output | Channel 2 low-side gate driver output for the low-side power MOSFET, rated for 0.8 A source and 1.3 A sink peak (pulse width ≤10 µs). |
| 20 | NC | unconnected | No connection; leave floating. |
| 21 | NC | unconnected | No connection; leave floating. |
| 22 | VS1 | power_in | Floating high-side ground reference for channel 1 (high-side source node). |
| 23 | HO1 | output | Channel 1 high-side gate driver output for the high-side power MOSFET, rated for 0.8 A source and 1.3 A sink peak (pulse width ≤10 µs). |
| 24 | VB1 | power_in | Floating high-side bootstrap supply for channel 1, referenced to VS1. |
