Overview
The DRV8817DAPR is a three-phase brushless DC motor driver manufactured by Texas Instruments. It integrates high-side and low-side N-channel power MOSFETs to drive BLDC motors in various configurations, including six-step commutation and sinusoidal control. The device features an integrated charge pump for gate drive, enabling efficient operation at low voltages. It includes protection mechanisms such as overcurrent protection, thermal shutdown, and undervoltage lockout to ensure reliable performance in demanding industrial and consumer applications.
Feature Summary
- Integrates high-side and low-side N-channel power MOSFETs for direct BLDC motor driving
- Supports multiple commutation modes including six-step and sinusoidal control
- Includes built-in protection against overcurrent, thermal overload, and undervoltage conditions
Applications
- Industrial automation systems requiring precise motor control
- Consumer appliances with brushless DC motor drives
- Medical equipment needing reliable and compact motor solutions
Procurement Notes
Verify the exact package type and tape/reel specifications against the official datasheet before ordering. Confirm that the component meets all required environmental and safety standards for your specific application. Ensure compatibility with your system's voltage and current requirements.
Selection Notes
Consider the DRV8817DAPR when designing systems that require integrated BLDC motor control with minimal external components. Evaluate its protection features and commutation capabilities against your specific motor and load requirements. Compare it with other drivers in the DRV88xx series if different pinouts or features are needed.
Part Context
The DRV8817DAPR belongs to Texas Instruments' DRV88xx family of motor drivers, which are designed for various brushless DC motor applications. This family offers integrated solutions to simplify design and reduce board space. The DAPR suffix indicates a specific tape and reel packaging option suitable for automated assembly processes.
Replacement Considerations
Check for direct pin-to-pin replacements within the DRV88xx series, such as the DRV8815 or DRV8819, depending on current and voltage requirements. Verify that any substitute part supports the same commutation modes and protection features.
