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.
