EG Micro · Gate Drivers · SSOP-24

EG2129 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 Logic input for the channel 1 high-side MOS transistor, active high: 1 turns the high-side switch on and 0 turns it off.
2 LIN1 input Logic input for the channel 1 low-side MOS transistor, active high: 1 turns the low-side switch on and 0 turns it off.
3 HIN2 input Logic input for the channel 2 high-side MOS transistor, active high: 1 turns the high-side switch on and 0 turns it off.
4 LIN2 input Logic input for the channel 2 low-side MOS transistor, active high: 1 turns the low-side switch on and 0 turns it off.
5 SD1 bidirectional Active-low logic signal that forces LO1 and HO1 outputs low when pulled low.
6 SD2 bidirectional Active-low logic signal that forces LO2 and HO2 outputs low when pulled low.
7 CINN1 input Negative input of comparator 1; comparator input voltage range is 0.1 V to VCC.
8 CINP1 input Positive input of comparator 1; comparator input voltage range is 0.1 V to VCC.
9 CINN2 input Negative input of comparator 2; comparator input voltage range is 0.1 V to VCC.
10 CINP2 input Positive input of comparator 2; comparator input voltage range is 0.1 V to VCC.
11 VCC power_in Chip supply input, 10 V to 20 V; decouple with a high-frequency bypass capacitor to reduce high-frequency noise at the input.
