DRV10983PWPR

Overview

The DRV10983PWPR is a three-phase sensorless BLDC motor controller and driver manufactured by Texas Instruments. It integrates power MOSFETs to deliver a continuous drive current of 2A, with peak capability up to 3A. The device operates within an input voltage range of 8V to 28V and features a total H+L rDS(on) of 250mΩ. Designed for surface-mount applications, it utilizes a 24-pin HTSSOP package with exposed thermal pad. The operational temperature range spans from -40°C to +125°C, and the quiescent supply current is specified at 11mA.

Feature Summary

• Proprietary sensorless control scheme providing continuous sine wave 180° commutation to minimize audible noise during switching.
• Integrated buck/linear regulator efficiently steps down supply voltage to provide 5V or 3.3V power for internal and external circuits.
• Flexible user interface supporting I2C, analog, or PWM inputs for motor control, with FG pin or I2C for speed feedback.
• Comprehensive protection mechanisms including overcurrent protection, lock detection, voltage surge protection, UVLO, and thermal shutdown.

Applications

• Home appliances
• Fan systems
• Pump drives

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 24-pin HTSSOP footprint matches the target PCB design, paying attention to the exposed thermal pad requirements for adequate heat dissipation. Ensure the selected component variant aligns with the necessary standby or sleep mode specifications if power efficiency is a critical design constraint.

Selection Notes

Select this component when designing cost-sensitive, low-noise applications requiring minimal external components. It is suitable for systems needing integrated control and power stages without external sensing resistors. Consider the available interface options (I2C, PWM, Analog) based on the host microcontroller capabilities. Evaluate the thermal performance in the final enclosure, as the device relies on the PCB copper area for heat management through the exposed pad.

Part Context

This part belongs to the DRV10983 series, which includes variants such as the standard DRV10983PWP and the low-power DRV10983ZPWP. The PWPR suffix specifically denotes the reel-packaged version of the standard device. It is distinct from higher-current counterparts like the DRV10987 series. The series is designed for single-supply operation and integrates all necessary functions for driving three-phase brushless motors.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Designers should consult official cross-reference data or contact the manufacturer directly for validated alternatives.
