DRV10987SPWPR

Overview

The DRV10987SPWPR is a three-phase sensorless brushless DC motor controller manufactured by Texas Instruments. It operates within a supply voltage range of 6.2 V to 28 V and delivers a continuous output current of 2 A with a peak capability of 3 A. The device utilizes an HTSSOP-24 package and supports I2C and USB interfaces for configuration. It features integrated power MOSFETs with a total driver H+L RDS(on) of 250 mΩ at 25°C. The operating temperature range spans from -40°C to +125°C, and the quiescent supply current is 13 mA.

Feature Summary

• Patented sensorless control scheme providing continuous sine drive to reduce audible noise
• Integrated buck regulator stepping down voltage to 5V for internal circuitry
• Configurable PWM conversion rates and frequencies for electromagnetic interference management
• Initial position detection algorithm to prevent centrifugal startup issues

Applications

• Floor fans and ceiling fans
• Air purifiers and humidifiers
• Drying cycle fans
• Drainage and water pumps

Procurement Notes

Verify the specific suffix 'SP' against official datasheets to confirm it denotes the standard operational variant rather than the low standby current (S) or deep sleep (D) versions. Confirm the HTSSOP-24 package type matches your PCB footprint requirements. Ensure the evaluation module DRV10987EVM is available if initial tuning is required for your specific motor parameters.

Selection Notes

Select this component when designing systems requiring low-noise operation for BLDC or PMSM motors in fan and pump applications. It is suitable for cost-sensitive designs needing minimal external components due to integrated power stages and regulators. Consider the I2C interface for flexible parameter tuning via EEPROM if dynamic adjustment is necessary during operation.

Part Context

This part belongs to the DRV10987 family of three-phase motor drivers. It shares the core architecture with variants like the DRV10987S and DRV10987D, which offer reduced standby currents. The DRV10983 serves as a related but distinct controller with different current capabilities and feature sets. This specific model focuses on balancing performance with low acoustic emissions.
