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 –5V 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 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 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.
