DRV10975PWP

Overview

The DRV10975PWP is a three-phase, sensorless brushless DC motor driver designed for 12-V nominal applications. It integrates a full-bridge power stage capable of delivering up to 3-A peak output current. The device supports sinusoidal commutation and accepts analog, PWM, or I2C control interfaces. It operates within a supply voltage range of 6.5 V to 18 V and functions across an extended temperature range from -40°C to +125°C. Packaged in a 24-pin HTSSOP with an exposed thermal pad, it includes built-in protection features such as overcurrent, overvoltage, and thermal shutdown.

Feature Summary

• Integrates a high-side/low-side gate driver and N-channel power MOSFETs for a complete three-phase drive solution
• Supports sensorless field-oriented control with sinusoidal commutation for smooth motor operation
• Provides flexible input interface options including analog speed control, PWM modulation, and I2C configuration
• Includes comprehensive protection mechanisms against overcurrent, overvoltage, undervoltage lockout, and overheating

Applications

• Home appliance fans and blowers
• Computer cooling systems
• Industrial automation equipment
• HVAC fan motors

Procurement Notes

Verify the specific suffix 'PWP' corresponds to the HTSSOP-24 package variant when sourcing. Confirm that the required orderable part number matches the exact pinout and thermal characteristics specified in the official Texas Instruments datasheet. Ensure compatibility with the intended control interface signals before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring integrated power switching without external drivers. It is suitable for designs needing sensorless control to reduce system cost and complexity. Consider the thermal performance of the HTSSOP package relative to the expected continuous current load. Verify that the operating voltage range aligns with the available power supply rails in the target system architecture.

Part Context

This device belongs to the DRV1097x family of sensorless BLDC motor drivers from Texas Instruments. It shares architectural similarities with other members like the DRV10975RHFR but differs in packaging. The family targets low-to-medium power motor control applications where space constraints and integration levels are critical design factors.

Replacement Considerations

The DRV10975RHFR serves as a direct functional equivalent with identical electrical specifications, differing only in the VQFN-24 package versus the HTSSOP-24 form factor.
