3 Description

The UCC27517A-Q1 single-channel high-speed low-

side gate-driver device effectively drives MOSFET and IGBT power switches. With a design that

inherently minimizes shoot-through current, the

UCC27517A-Q1 sources and sinks high peak-current

pulses into capacitive loads offering rail-to-rail drive

capability and extremely small propagation delay

typically 13 ns.

The UCC27517A-Q1 device handles –5 V at input.

The UCC27517A-Q1 provides 4-A source and 4-A

sink (symmetrical drive) peak-drive current capability

at VDD = 12 V.

The UCC27517A-Q1 operates over a wide VDD range

of 4.5 V to 18 V and wide temperature range of –40°C to 140°C. Internal Undervoltage Lockout

(UVLO) circuitry on VDD pin holds the output low

outside VDD operating range. The ability 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.
