3 Description

The UcC27516 and UcC27517 single-channelhigh
speed, low-side gate driver devices caneffectively
drive Mosfet and IGBT powerswitches.Using a
design thatinherently minimizesshoot-through
current,UcC27516 and UCC27517 can sourceand
sink high peakcurrent pulses into capacitive loads
offering rail-to-rail drive capability and extremely small
propagation delay, typically 13 ns.
The UcC27516 and UcC27517 provides 4-A source
4-A sink (symmetrical drive)peak-drive current
capability at VDD =12 V.
