Texas Instruments DRV8305NPHPQ1 | Demoboard BOOSTXL-DRV8323RS

Description

The BOOSTXL-DRV8323RS is a 15A, 3-phase brushless DC drive stage based on the DRV8323RH gate driver and CSD88599Q5DC NexFETTM power blocks. The module has individual DC bus and phase voltage sense as well as individual low-side current shunt amplifiers, making this evaluation module ideal for sensorless BLDC algorithms. The module supplies MCU 3.3V power with an integrated 0.6A step down buck regulator. The drive stage is fully protected with short circuit, thermal, shoot-through, and under voltage protection and easily configurable via the devices SPI registers.
