Half-bridge gate driver improves power system performance in hybrid vehicles

Introduced as the industry’s fastest 120V automotive grade half-bridge gate driver with robust handling features, Texas Instruments (TI) has unveiled the UCC27201A-Q1. The driver provides a propagation delay at 15ns with short rise and fall times and the tightest delay matching of 1ns for 12-V to 48-V DC/DC power supplies. The UCC27201A-Q1 high-side / low-side gate driver offers advanced noise tolerance, resulting in improved overall system performance for hybrid vehicles. The UCC27201A-Q1 is the only automotive gate driver to offer negative voltage handling capability on the high-side pin, making the product more immune to noise. An integrated 120V bootstrap diode also allows for N-channel MOSFET control and eliminates the need for external discrete diodes, says the company.
