**onsemi** · Gate Drive ICs · SOIC-8

MC34151DG from onsemi, in a SOIC-8. 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 | N.C. | unconnected | Marked N.C. (no connection) in the pin connections; the datasheet gives no function or limit for this pin. |
| 2 | Logic Input A | input | Logic input for Drive Output A with about 170 mV hysteresis around a 1.67 V threshold, accepting signals from ground to VCC; for optimum switching speed the maximum input voltage should be limited to 10 V or VCC, whichever is less. |
| 3 | GND | power_in | Ground reference for the logic inputs and drive outputs; VCC bypass capacitors should be connected with short leads as close to the VCC pin and ground as the layout permits. |
| 4 | Logic Input B | input | Logic input for Drive Output B with about 170 mV hysteresis around a 1.67 V threshold, accepting signals from ground to VCC; for optimum switching speed the maximum input voltage should be limited to 10 V or VCC, whichever is less. |
| 5 | Drive Output B | output | Inverting totem-pole drive output capable of sourcing and sinking up to 1.5 A, with no overcurrent or thermal protection, so shorting the output to VCC or ground must be avoided. |
| 6 | VCC | power_in | Supply pin with a 6.5 V to 18 V operating voltage and a 20 V maximum rating; the undervoltage lockout forces the drive outputs low as VCC rises from 1.4 V to the 5.8 V upper threshold (5.3 V lower threshold). |
| 7 | Drive Output A | output | Inverting totem-pole drive output capable of sourcing and sinking up to 1.5 A, with no overcurrent or thermal protection, so shorting the output to VCC or ground must be avoided. |
| 8 | N.C. | unconnected | Marked N.C. (no connection) in the pin connections; the datasheet gives no function or limit for this pin. |
