MIC4129YME
Microchip Tech · Gate Drive ICs · SOIC-8-EP
MIC4129YME from Microchip Tech, 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 | VS | power_in | Supply input (4.5V to 20V operating); duplicate pins 1 and 8 must be externally connected together. |
| 2 | IN | input | Control input accepting logic levels from 2.4V to VS and tolerating swings down to 5V below ground; the MIC4129 output is inverted relative to it. |
| 3 | NC | unconnected | Not connected. |
| 4 | GND | power_in | Ground; duplicate pins 4 and 5 must be externally connected together. |
| 5 | GND | power_in | Ground; duplicate pins 4 and 5 must be externally connected together. |
| 6 | OUT | output | Driver output capable of 6A peak; duplicate pins 6 and 7 must be externally connected together. |
| 7 | OUT | output | Driver output capable of 6A peak; duplicate pins 6 and 7 must be externally connected together. |
| 8 | VS | power_in | Supply input (4.5V to 20V operating); duplicate pins 1 and 8 must be externally connected together. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
