DRV10866DSCR

Overview

The DRV10866DSCR is a sensorless brushless DC motor driver manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and delivers an output current of 800 mA. The device functions in a three-phase configuration with two outputs, consuming 2.5 mA during operation. It supports surface-mount installation in a WSON-10 package and withstands operating temperatures from -40°C to +85°C.

Feature Summary

• Sensorless control architecture for brushless DC motors
• Three-phase output configuration
• Low quiescent current consumption

Applications

• Fan motor control systems
• Pump drive applications
• Small appliance motor drivers

Procurement Notes

Verify the specific suffix DSCR against the manufacturer datasheet to confirm reel packaging specifications and moisture sensitivity level requirements. Ensure compatibility with the target PCB footprint for the WSON-10 package. Confirm that the input voltage range aligns with the system power supply design before finalizing procurement orders.

Selection Notes

Select this component when designing compact BLDC motor drives requiring low standby power and minimal external components. The integrated sensorless control eliminates the need for Hall effect sensors, reducing bill of materials cost. Verify that the 800 mA output capability meets the peak load requirements of the intended motor application.

Part Context

This part belongs to the DRV10866 series of motor controllers. It is distinct from other TI motor drivers by its specific focus on low-voltage, low-current sensorless applications. The DSCR suffix indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin compatible alternatives within the same family. Verify electrical parameter equivalence for any cross-brand substitutes.
