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.
