7.1 Overview

The UCC27332-Q1 deviceis a single-channel, high-speed, gate drivers capable of effectively driving MOSFET, and GaN power switches with 9-A source and 9-A sink (symmetrical drive) peak current. A strong source and sink capability boost immunity against a parasitic Miller turnon effect. The UCC27332-Q1 device can be directly connected to the gate driver transformer or line driver transformer as the inputs of UCC27332-Q1 can handle –5V. The driver has a good transient handling capability on its output due to reverse currents, as well as rail-to-rail drive capability and small propagation delay, typically 23 ns.

The input threshold of UCC27332-Q1 is compatible to TTL low-voltage logic, which is fixed and independent of VDD supply voltage. The driver can also work with CMOS based controllers as long as the threshold requirement is met. The 1-V typical hysteresis offers excellent noise immunity.

The driver has an EN pin with fixed TTL compatible threshold. EN is internally pulled up; pulling EN low disables the driver, while leaving EN open provides normal operation. The EN pin can be used as an additional input with similar performance as the IN pin.
