DRV10983QPWPRQ1

Overview

The DRV10983QPWPRQ1 is an automotive-qualified, three-phase sensorless BLDC motor driver from Texas Instruments. It integrates power MOSFETs to deliver a continuous drive current of 2 A with a peak capability of 3.5 A. The device operates within a supply voltage range of 6.2 V to 28 V and supports I2C, PWM, and analog interfaces. It features a proprietary sensorless control scheme for continuous sine wave commutation, reducing acoustic noise. The component includes an integrated buck/linear regulator for internal and external circuitry, offering standby and sleep modes for power efficiency.

Feature Summary

• Proprietary sensorless control providing continuous sine wave commutation to minimize acoustic noise
• Integrated power stage with high-side and low-side MOSFETs eliminating the need for external sensing resistors
• Flexible user interface supporting I2C, PWM, and analog inputs for speed and direction control
• Built-in protection mechanisms including overcurrent protection, lock detection, undervoltage lockout, and thermal shutdown

Applications

• Automotive seat ventilation fans
• Motorcycle fuel pumps
• Hybrid electric vehicle (HEV) battery cooling fans
• Small industrial water pumps
• Low-noise fan systems

Procurement Notes

Verify the specific suffix 'QPWPRQ1' against the official datasheet to confirm the package type, temperature grade, and automotive qualification status. Ensure that the required operating voltage and current ratings align with the target application's electrical specifications before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring cost-sensitive, low-noise BLDC motor control with minimal external components. It is suitable for designs needing integrated power management and flexible interface options. Consider the HTSSOP-24 package constraints and thermal requirements when designing the PCB layout for optimal heat dissipation.

Part Context

This part belongs to the DRV10983 family of sensorless BLDC motor drivers. It is specifically designed for automotive environments, meeting AEC-Q100 standards. The QPWR variant indicates a tape and reel packaging format, while the Q1 suffix denotes automotive qualification. It serves as a complete solution for driving three-phase motors without external gate drivers or current sense amplifiers.

Replacement Considerations

The non-automotive version DRV10983PWPR offers similar functionality but lacks automotive qualification. For direct replacements, verify if the DRV10983Z variants are suitable, noting differences in standby versus sleep mode power consumption characteristics.
