Texas Instruments delivers automotive gate drivers with industry’s fastest propagation delays


PrintTexas Instruments (TI) today introduced six, AEC-Q100-qualified gate drivers with industry’s fastest propagation delays of less than 15 nanoseconds. The UCC275xx-Q1 family of single- and dual-channel gate drivers provides the highest power efficiency, reliability and flexibility compared to existing solutions for automotive applications, such as powertrain, bi-directional converters (12- to 48-V and 12- to 400-V input), onboard charging, traction inverters, advanced driver assistance systems (ADAS), safety, headlamps and instrumentation clusters. The ultra-low propagation delays in the UCC275xx-Q1 family help automotive systems efficiently switch power electronics at high frequencies to maintain a small footprint and reduce overall vehicle weight.

The UCC275xx-Q1 gate drivers present an integrated solution that saves space and enables highest efficiency: with peak currents ranging from 2.5 A to 5 A and propagation delays of less than 15 ns, TI’s automotive output-stage drivers can replace discrete totem pole solutions. They are also flexible in design to support a wide input voltage range: supports 4.5 V to 35 V to drive wide bandgap switches, such as SiC, MOSFETs and IGBTs that are capable of withstanding high temperatures without compromising efficiency. Finally the UCC275xx-Q1 family by Texas Instruments is reliable and robust: the wide temperature range of -40 to 140 degrees Celsius and negative input voltage of -5 V enables handling of ground bouncing experienced in harsh environments.

Samples and production quantities are available now. Designers can get started today on designing with the UCC27531-Q1 by ordering the UCC27531EVM-184 evaluation module for US$49.00. The UCC27532EVM-538 is available for US49.00. In addition to a PSpice model, two TINA-TI SPICE simulation models for the UCC27531-Q1 help simplify design. The UCC27532-Q1 has a POWERSTAGE-DESIGNER development tool.
