3 Description

The UCC2752x family of devices are dual-channel, high-speed, low-side gate-driver devices capable of effectively driving MOSFET. and IGBT power switches. Using a design that inherently minimizes shoot-through current, UCC2752x can deliver high- peak current pulses of up to 5-A source and 5-A sink into capacitive loads along with rail-to-rail drive capability and extremely small propagation delay (typically 13 ns). In addition, the drivers feature matched internal propagation delays between the two channels.' These delays are very well suited for applications requiring dual-gate drives with critical timing，such as synchronous rectifiers. This also enables connecting two channels in parallel to effectively increase current-drive capability or driving two switches in parallel with one input signal. The input pin thresholds are 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.
