DESCRIPTION
•
•
Hysteretic-Logic Thresholds for High Noise
Immunity
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 is capable of
delivering 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 which 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 a single 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.
