3 Description
The UCC27524 device is a dual-channel, high-speed,
low-side, gate-driver device capable of effectively
driving MOSFET and IGBT power switches. The
UCC27524 adds the ability to handle –5V directly
at the input pins for increased robustness. The
UCC27524 is a dual non-inverting driver. Using
a design that inherently minimizes shoot-through
current, the UCC27524 is capable of delivering
high-peak 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 17ns. 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 currentdrive
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.
