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 highpeak

current pulses of up to 5A source and 5A

sink into capacitive loads along with rail-to-rail drive

capability and extremely small propagation delay

(typically 13ns). 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.
