Gate drivers boost powertrain performance with start-stop support and high-temperature operation
DALLAS, June 15, 2016 — (PRNewswire) — Texas Instruments (TI) (NASDAQ: TXN) today introduced two new automotive motor drivers that support high-performance powertrain applications. The DRV8305-Q1, a highly integrated three-phase brushless DC gate driver, and the UCC27211A-Q1, a high-current half-bridge gate driver, improve system performance and provide design flexibility to meet a diverse range of automotive system requirements. For more information and to order samples, visit http://www.ti.com/DRV8305-Q1-pr and http://www.ti.com/UCC27211A-Q1-pr.
For powertrain applications such as transmission pumps or engine cooling fans, the DRV8305-Q1 features a smart gate-drive architecture with programmable slew-rate control that allows easy optimization of MOSFET electromagnetic compliance (EMC). With an operating ambient temperature range of -40 to 150°C, the DRV8305-Q1 meets the Automotive Electronics Council (AEC)-Q100 Grade 0 automotive temperature specification. Other features and benefits include the following:
- Start-stop support: The device operates down to 4.4 V to support start-stop functionality, which enables car manufacturers to meet strict fuel efficiency and carbon-dioxide emission standards.
- Reduced board space: The DRV8305-Q1's integrated 3.3V or 5V linear regulator, three current-sense amplifiers and smart gate-drive architecture reduces board size and eliminates up to 20 external components.
- Fault protection: Advanced on-chip protection with detailed fault diagnostics guard against overtemperature, undervoltage lockout, MOSFET shoot-through and overcurrent events.
For automotive designers looking for design flexibility, the 100-V UCC27211A-Q1 half-bridge gate driver supports both brushed and brushless DC motor applications. Designing with individual half bridges allows placement of the gate driver close to the MOSFETs, minimizing parasitic inductances and simplifying overall board layout. Additionally, it offers the following benefits:
- Leading performance: With the industry's fastest propagation delays at 15 ns, fast rise and fall times of 7 ns and a 4-A peak gate drive, the device packs high performance into a small 4.89-mm-by-3.9-mm package size.
- Robust protection: The UCC27211A-Q1's negative voltage rating of -12V protects the driver from potentially damaging voltage spikes.
The DRV8305-Q1 and UCC27211A-Q1 expand TI's robust portfolio of motor drivers that offer designers integrated, flexible solutions across a broad range of voltage, current, interface, integration and control options.
