Two new motor drivers for automotive brushless DC motors

TI (CEO Kent Tran) announced the launch of two new automotive motor drivers to support high-performance powertrain applications.

The highly integrated 3-phase brushless DC gate driver DRV8305-Q1 and the high-current half-bridge gate driver UCC27211A-Q1 improve system performance and provide design flexibility to meet a wide range of automotive system requirements.

Suitable for powertrain applications such as transmission pumps or engine cooling fans, the DRV8305-Q1 features a smart gate-drive architecture and allows for easy optimization of MOSFET Electromagnetic Compliance (EMC) through programmable slew rate control. Operating over an ambient temperature range of -40 to 150°C, the DRV8305-Q1 meets automotive temperature standards with AEC-Q100 Class 0. In addition, it offers the following features and advantages:


This device can operate up to 4.4V and supports a start-stop function, so automotive manufacturers can meet strict fuel efficiency and CO2 emission standards.

In addition, the DRV8305-Q1 integrates a 3.3V or 5V linear regulator and three current sensing amplifiers, and adopts a smart gate-drive architecture to save board space and eliminate up to 20 external components. It features built-in advanced protection capabilities with close error diagnosis and monitoring to protect the chip from overheating, undervoltage lockout, MOSFET shoot-through, and overcurrent conditions.

The 100V UCC27211A-Q1 half-bridge gate driver, designed for automotive developers seeking design flexibility, supports both brushed and brushless DC motor applications. The discrete half-bridge design allows the gate driver to be placed close to the MOSFET, minimizing parasitic inductance and simplifying the overall board layout.

The DRV8305-Q1 and UCC27211A-Q1 expand TI's robust motor driver portfolio by providing developers with flexible integrated solutions across a wide range of voltage, current, interface, integration, and control options.
