DRV8306HRSMR

DRV8306HRSMR is TI’s 3-phase brushless DC motor gate-driver IC. It provides six drive outputs to control a three-phase bridge (external MOSFETs) from a microcontroller’s PWM signals, enabling BLDC/PMSM motor control without a separate DSP.
Key features (typical):
- Six high-current gate-drive channels (three half-bridges)
- Programmable current limit and current regulation
- Protections: undervoltage lockout, overcurrent, overtemperature
- Fault reporting/diagnostics (status pins to MCU)
- Suitable for sensorless or Hall-sensorless BLDC control with simple interface
- RoHS-compliant HRSM package variant
Applications:
- Robotics, drones, automotive, industrial motors, and other BLDC/PMSM drives
Note: The HRSM suffix indicates a specific TI package variant. For exact electrical specs (supply range, timing, and pinout), consult the DRV8306 datasheet and TI’s packaging document.

Key features of DRV8306HRSMR:
- 3-phase motor driver with integrated high-/low-side MOSFETs for BLDC/PMSM use
- Programmable current regulation via sense resistor for torque control
- PWM/step control with configurable dead time and decay modes
- SPI/config registers for setup and status readback
- Fault and diagnostics: latched FAULT/STATUS, programmable fault response
- Protections: undervoltage lockout, overcurrent, overtemperature, short-to-GND/short-to-VS, shoot-through prevention
- Brake and enable/disable functionality
- Robust, compact HTSSOP-style package (HRSMR) for easy integration
