The UCC27512 single-channel, high-speed, low-side gate driver device is capable of
effectively driving MOSFET and IGBT power switches. Using a design that inherently minimizes
shoot-through current, UCC27512 is capable of sourcing and sinking high, peak-current pulses into
capacitive loads offering rail-to-rail drive capability and extremely small propagation delay
typically 13 ns.
The UCC27512 provides 4-A source, 8-A sink (asymmetrical drive) peak-drive current
capability. Strong sink capability in asymmetrical drive boosts immunity against parasitic, Miller
turn-on effect.
UCC27512 is designed to operate over a wide VDD range of 4.5 V to 18 V and wide
temperature range of 55°C to 125°C. Internal Under Voltage Lockout (UVLO) circuitry on 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.
