Overview

The DRV10974 device is a three-phase sensorless motor driver with integrated power MOSFETs, which can provide continuous drive current up to 1 A (rms). The device is designed for cost-sensitive, low-noise, and low-external-component-count applications.

  • 1 Input Voltage Range: 4.4 V to 18 V
  • Total Driver H + L rDS(on): 750 mΩ (Typical) at TA = 25°C
  • Phase Drive Current: 1-A Continuous (1.5-A Peak)
  • 180° Sinusoidal Commutation for Optimal Acoustic Performance
  • Resistor-Configurable Lead Angle
  • Resistor-Configurable Current Limit
  • Soft Start With Resistor-Configurable Acceleration Profile
  • Built-In Current Sense to Eliminate External Current-Sense Resistor
  • Proprietary Sensorless Control Without Motor Center Tap
  • Simple User Interface: - One-Pin Configuration for Start-Up - PWM Input Designates Magnitude of Voltage Applied to Motor - Open-Drain FG Output Provides Speed Feedback - Pin for Forward and Reverse Control
