DRV8306HRSMR

The DRV8306HRSMR is TI’s three‑phase brushless DC motor driver with integrated MOSFETs, designed to drive BLDC/PMSM motors from a single device. It provides three high/low‑side switch pairs in one package, plus gate drive, current sensing/feedback, and built‑in protections, simplifying motor control with a microcontroller.
Key features (typical):
- 3-phase full-bridge with integrated FETs
- PWM/gate‑drive control and current regulation/feedback
- Protections: UVLO/OV, overcurrent, overtemperature, short-to-ground/Vbus
- Fault reporting and status indications
- Supports sensorless or Hall-effect commutation; configurable decay and deadtime
Applications:
- Automotive and industrial BLDC/PMSM motor drives, pumps, fans, robotics
Packaging:
- HRSMR denotes the specific TI packaging variant (rohs-compliant surface-mount with the associated temperature rating)
Note: For exact electrical specs (voltage range, current, timing), consult the DRV8306HRSMR datasheet.

Key features of DRV8306HRSMR (TI three‑phase motor driver with integrated FETs):
- 3-phase motor drive with six integrated MOSFETs and gate drivers for BLDC motors.
- Wide supply range and robust protection: UVLO, OVP, OCP, overtemperature, short‑to‑ground/short‑to‑Vs protection.
- Cycle‑by‑cycle current regulation for programmable torque control using an external sense resistor.
- PWM-compatible inputs per phase with soft‑start and programmable current decay/braking modes.
- Fault reporting and diagnosis with latchable fault outputs (e.g., nFAULT) for microcontroller monitoring.
- Dead‑time insertion and protection against shoot‑through for safe operation.
- Optional braking/coasting modes and regenerative behavior for energy recovery.
- Suitable for microcontroller interfaces with simple control signals (no complex SPI required in many configurations).
- Compact package (HRSMR) ideal for compact motor drive assemblies.
Note: Specific electrical limits (voltage range, current capability) are device‑level; consult the datasheet for exact numbers.
