Texas Instruments  DRV3205QPHPRQ1

The DRV3205-Q1 bridge driver is dedicated to automotive three-phase brushless DC motorcontrol applications. The device provides six dedicated drivers for standard-level N-channel MOSFETtransistors. A boost converter with an integrated FET provides the overdrive voltage, allowing fullcontrol on the power stages even for low battery voltage down to 4.75 V. The strong driver strengthis suitable for high-current applications and programmable to limit peak output current.

The device incorporates robust FET protection and system monitoring functions like aQ&A watchdog and voltage monitors for I/O supplies and ADC reference voltages. Integratedinternal diagnostic functions can be accessed and programmed through an SPI interface.
