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 17 ns. In addition, the drivers feature
matched internal propagation delays between the two
channels which are very well suited for applications
requiring dual-gate drives with critical timing, such as
synchronous rectifiers. The input pin thresholds are
based on CMOS logic, which is a function of the VDD
supply voltage. Wide hysteresis between the high and
low thresholds offers excellent noise immunity. The
Enable pins are based on TTL and CMOS compatible
logic, independent of VDD supply voltage.
