The UCC37322P delivers 9 A peak source and sink current with 20 ns typical rise and fall times, so it charges and discharges the MOSFET gate capacitance fast enough to keep switching losses low in a 100–500 kHz converter or a hard-switched motor-drive leg. Supply range is 4 V to 15 V, which covers both 5 V logic rails and 12 V gate-drive bias — no extra level shifter needed when the controller runs at 3.3 V and the power stage needs 10 V on the gate. It drives N-channel and P-channel MOSFETs in a low-side configuration, so it handles the ground-referenced switch in a buck converter, a synchronous rectifier, or a push-pull stage where the source returns to ground.
