Texas Instruments (TI) has introduced two new automotive motor drivers that support high-performance powertrain applications.
The DRV8305-Q1, an integrated three-phase brushless DC gate driver, and the UCC27211A-Q1, a high-current half-bridge gate driver, are designed to improve system performance and provide design flexibility for a range of automotive system requirements.
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). It offers an operating temperature range of -40 to 150° C, and also operates down to 4.4 V to support start-stop functionality.
The DRV8305-Q1’s integrated 3.3 V or 5 V linear regulator, three current-sense amplifiers and smart gate-drive architecture reduces board size and eliminates up to 20 external components, according to TI.
On-chip protection features detailed fault diagnostics to guard against over-temperature, under-voltage lockout, MOSFET shoot-through and over-current events.
