Description
General part information
UCC44273 Series
The UCC44273 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, the UCC44273 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 UCC44273 device is capable of handling –5 V at the input pins. The UCC44273 provides 4-A source and 4-A sink (symmetrical drive) peak-drive current capability at VDD = 12 V.
The UCC44273 is designed to operate 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 output low outside VDD operating range.
