Texas Instruments DRV3220-Q1 Three-Phase Automotive Gate Driver
Texas Instruments DRV3220-Q1 Three-Phase Automotive Gate Driver is ideal for three-phase brushless DC motor control applications. Offering six dedicated drivers for standard-level N-channel MOSFET transistors, the DRV3220-Q1 also provides a boost converter with an integrated FET creating the overdrive voltage. This allows the device to have complete control on the power stages even for low battery voltage down to 4.75V. The DRV3220-Q1 strong driver strength is developed for high-current applications and programmable to limit peak output current. Features include robust FET protection and system monitoring functions like a Q&A watchdog and voltage monitors for I/O supplies and ADC reference voltages. The DRV3220-Q1 integrated internal diagnostic procedures can be accessed and programmed through an SPI interface.
