Overview
The DRV8307RHAT is a three-phase brushless DC motor controller featuring a pre-driver that drives six N-type MOSFETs with a 30 mA gate-drive current. It operates on a single power supply ranging from 8.5 V to 32 V and accepts a single PWM input for speed control. The device supports integrated commutation logic with three Hall sensor inputs and includes an integrated current sense amplifier for protection. A separate 5 V regulator powers external components such as Hall sensors.
Feature Summary
- Integrated commutation logic supporting three Hall sensor inputs
- Built-in current sense amplifier for overcurrent protection
- Dedicated 5 V regulator for powering external sensors
- Single PWM input interface for simplified speed control
Applications
- Sensored three-phase brushless DC motor control
- Industrial automation drive systems
- Consumer appliance motor management
Procurement Notes
Verify the specific suffix RHAT against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure the design accommodates the 8.5 V to 32 V operating range and validates thermal performance for the VQFN-40 package under expected load conditions. Cross-reference the latest revision history for any pinout or electrical parameter updates.
Selection Notes
Select this component when designing sensored BLDC applications requiring a dedicated pre-driver with integrated commutation logic. It is suitable for systems needing a single PWM input and built-in current limiting without complex digital configuration. Consider the DRV8308 if adjustable slew rates, higher gate drive current, or fully digital speed loop capabilities are required instead.
Part Context
This part belongs to the DRV8307/8 family of three-phase brushless DC motor controllers manufactured by Texas Instruments. The DRV8307 variant focuses on analog simplicity with fixed gate drive strength, contrasting with the DRV8308 which offers configurable digital features. Both devices target sensored motor applications but differ in control complexity and output drive capabilities.
Replacement Considerations
The DRV8308 serves as a functional upgrade within the same family, offering higher gate drive current and digital speed loop features. Direct pin-compatible substitutes are not explicitly confirmed in public documentation; verify compatibility carefully before substitution.
