DESCRIPTION

•

Hysteretic-Logic Thresholds for High Noise

Immunity

The UCC27524A device is a dual-channel, high-

speed, low-side, gate-driver device capable of

effectively driving MOSFET and IGBT power

switches. The UCC27524A is a variant of the

UCC2752x family. The UCC27524A adds the ability

to handle -5 V directly at the input pins for increased

robustness. The UCC27524A is a dual non-inverting

driver. Using a design that inherently minimizes

shoot-through current, the UCC27524A 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.
