Product Introduction

Overview

The DRV10987SPWPR, produced by Texas Instruments, is a 12-V to 24-V nominal, 3-phase sensorless sinusoidal control BLDC (Brushless DC) motor driver. This device is designed for cost-sensitive, low-noise, and low-external-component-count applications, particularly in fan and pump systems. It features integrated power MOSFETs, providing continuous drive current up to 2 A and peak current up to 3 A. The DRV10987SPWPR uses a proprietary sensorless control scheme to deliver continuous sinusoidal drive, reducing pure tone acoustics associated with commutation. The device is available in a thermally-efficient HTSSOP (PWP) package with 24 pins and an exposed thermal pad, operating within an ambient temperature range of –40°C to 125°C.

  • Flexible user interface options: I²C interface, dedicated SPEED pin (analog or PWM input), dedicated FG pin for TACH feedback.
  • Forward-reverse control with DIR pin.
  • Spin-up profile customizable with EEPROM.
  • Integrated buck converter (5 V, 100 mA) and LDO (3.3 V, 20 mA).
  • Thermally enhanced package with exposed thermal pad.

Applications

The DRV10987SPWPR is specifically designed for cost-sensitive, low-noise, and low-external-component-count applications. Key use cases include:

  • Fan systems: Ideal for applications requiring quiet and efficient fan operation.
  • Pump systems: Suitable for pump applications that need smooth and quiet operation.
  • Other motor control applications: Can be used in various motor control scenarios where sensorless sinusoidal control is beneficial.
