DRV10983SQPWPRQ1

Overview

The DRV10983SQPWPRQ1 is an automotive-grade, three-phase sensorless BLDC motor driver from Texas Instruments. It integrates power MOSFETs to deliver a continuous drive current of 2A with a peak capability of 3A. The device operates within a supply voltage range of 6.2V to 28V and supports an operating temperature range from -40°C to +125°C. It features a 24-pin HTSSOP package with exposed thermal pad for efficient heat dissipation. The component includes an integrated buck/linear regulator capable of outputting 5V or 3.3V for internal and external circuitry.

Feature Summary

• Utilizes proprietary sensorless control scheme providing continuous sine wave commutation to minimize audible noise during operation.
• Offers flexible user interface options including I2C for register access and EEPROM programming, alongside dedicated pins for analog/PWM speed input and tachometer feedback.
• Integrates comprehensive protection mechanisms such as overcurrent protection, lock detection, voltage surge protection, undervoltage lockout, and thermal shutdown.
• Features an integrated switching regulator that efficiently steps down supply voltage to provide stable power for internal logic and external microcontrollers.

Applications

• Automotive seat ventilation fans
• Motorcycle fuel pumps
• Hybrid electric vehicle battery cooling fans
• Small industrial water pumps

Procurement Notes

Verify the AEC-Q100 qualification status to ensure compliance with automotive reliability standards. Confirm the specific suffix indicates the intended sleep or standby mode variant if low-power consumption is critical for the design. Ensure the HTSSOP-24 footprint matches the PCB layout requirements, paying attention to the exposed thermal pad for adequate heat sinking. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component for applications requiring low-noise operation in cost-sensitive environments due to its sensorless sine commutation technology. It is suitable for systems needing integrated power management and multiple control interfaces. Consider the 2A continuous current rating against the load requirements. Evaluate the need for EEPROM customization to optimize performance for specific motor characteristics. Ensure the operating voltage range aligns with the system's power supply architecture.

Part Context

This part belongs to the DRV10983 family of brushless DC motor drivers designed for automotive and industrial applications. The 'SQ' suffix denotes automotive grade qualification under AEC-Q100 standards. The 'PWP' indicates the 24-pin HTSSOP package type. The 'RQ1' suffix typically signifies reel packaging and automotive qualification. This series focuses on reducing external component count while maintaining high efficiency and low acoustic noise.

Replacement Considerations

Check for other variants within the DRV10983 family, such as non-automotive grades or different package options, if automotive qualification is not required. Verify functional compatibility with alternative sensorless BLDC drivers offering similar current ratings and interface capabilities. Ensure any substitute maintains the same thermal performance and protection features.
