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.

The input pin threshold of the UCC44273 device is based on TTL and CMOS compatible low-voltage logic which is fixed and independent of the VDD supply voltage. Wide hysteresis between the high and low thresholds offers excellent noise immunity.
