3 Description

The UCC27518 and UCC27519 single-channel, high-

speed, low-side gate driver device can effectively

drive MOSFET and IGBT power switches. Using a

design that inherently minimizes shoot-through

current, UCC27518 and UCC27519 can source and

sink high, peak-current pulses into capacitive loads

offering rail-to-rail drive capability and extremely small

propagation delay typically 17 ns.

The UCC27518 and UCC27519 provide 4-A source,

4-A sink (symmetrical drive) peak-drive current capability at VDD = 12 V.

The UCC27518 and UCC27519 are designed to

operate over a wide VDD range of 4.5 V to 18 V and a wide temperature range of –40°C to 140°C. Internal

under voltage lockout (UVLO) circuitry on the VDD

pin holds output low outside VDD operating range.

The capability to operate at low voltage levels such

as below 5 V, along with best-in-class switching

characteristics, is especially suited for driving

emerging wide band-gap power switching devices such as GaN power semiconductor devices.
