Overview
The DRV10974PWP is a three-phase brushless DC motor controller and driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.4 V to 18 V and supports a peak output current of 2.5 A. The device features an HTSSOP-16 package and functions across a temperature range of -40°C to +125°C. Designed for sensorless sinusoidal control, it integrates power MOSFETs and requires a typical operating supply current of 5 mA.
Feature Summary
- Integrates full control logic and power stage for three-phase BLDC motors
- Supports sensorless sinusoidal commutation for smooth operation
- Includes built-in protection mechanisms against overcurrent and thermal events
Applications
- Fan and pump motor control systems
- Consumer appliance drive circuits
- Industrial motion control applications
Procurement Notes
Verify the specific suffix 'PWP' corresponds to the HTSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to surface mount construction. Cross-reference datasheet revision dates to guarantee parameter accuracy for design specifications.
Selection Notes
Select this component for designs requiring integrated sensorless control with moderate current demands up to 2.5 A peak. The wide operating voltage range accommodates various single-supply configurations. Evaluate thermal performance requirements based on the HTSSOP-16 package limitations in high-duty cycle scenarios. Consider the DRV10974EVM for initial validation of control algorithms.
Part Context
This part belongs to the DRV10974 family of motor drivers from Texas Instruments. It shares core functionality with variants like the DRV10974RUMR but differs in packaging. The family targets efficient, cost-effective solutions for three-phase BLDC motor applications in consumer and industrial sectors.
Replacement Considerations
The DRV10974RUMR serves as a functional alternative offering identical electrical characteristics in a 16-WQFN package. Verify pinout compatibility and thermal dissipation differences between the HTSSOP-16 and WQFN footprints before substitution.
