Overview
The DRV10975PWPR is a three-phase sensorless brushless DC motor driver manufactured by Texas Instruments. It operates within a supply voltage range of 6.5 V to 18 V and delivers a continuous output current of 1.5 A with a peak capability of 3 A. The device features an integrated power stage with half-bridge outputs and supports multiple control interfaces including analog, PWM, and I2C. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in a 24-pin HTSSOP package.
Feature Summary
- Integrates a proprietary sensorless control scheme for sinusoidal commutation without external sensing resistors
- Supports flexible user interface options via dedicated pins for analog/PWM input and tachometer feedback
- Includes built-in protection mechanisms such as overcurrent protection, lock detection, and thermal shutdown
Applications
- Home appliance fan motors
- Computer cooling systems
- Industrial automation equipment
Procurement Notes
Verify the specific suffix 'PWPR' corresponds to the HTSSOP-24 package and tape-and-reel quantity when ordering. Confirm that the application requires the 6.5 V minimum operating voltage rather than lower voltage variants. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference the datasheet revision date to ensure compatibility with existing design documentation.
Selection Notes
Select this component for applications requiring a balance between performance and cost in 12-V nominal systems. It is suitable where sensorless operation reduces bill-of-materials complexity. Consider the 1.5 A continuous current limit against motor load requirements. Evaluate the need for I2C programmability versus fixed analog control based on system architecture constraints.
Part Context
This part belongs to the DRV10975 family of three-phase BLDC drivers designed for low-noise, high-efficiency applications. It shares architectural similarities with the DRV10983 but targets specific voltage and current profiles for consumer electronics. The PWPR designation indicates the specific packaging format used for automated assembly processes.
Replacement Considerations
The DRV10975PWP is the non-reel version of the same device. The DRV10975RHFR offers the same functionality in a QFN package. Verify pinout compatibility before substituting with these alternatives.
