Texas Instruments (TI) has claimed the industry’s fastest 120-V automotive grade half-bridge gate driver with robust handling features. This 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 120-V bootstrap diode also allows for N-channel MOSFET control and eliminates the need for external discrete diodes.

Reduces cycle-by-cycle switching losses: Improves power-conditioning efficiency and allows the system to switch at high frequencies in hundreds of kilohertz, allowing for smaller system size and weight. Provides advanced noise toleration: The best negative-voltage handling at the switched-node pin creates the ability to tolerate noise, causing virtually no malfunctions in the electronic system. Drives MOSFETs over a wide power range: Allows the use of any MOSFET in multiple power levels.
UCC27201A-Q1 is now available in the TI store and through the company’s authorized distribution network. The UCC27201A-Q1 automotive gate driver comes in a small-outline integrated circuit (SOIC)-8 package and is priced at US$1.62 in 1,000 unit-quantities.
