Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community Reference Design DRV10975, DRV10975Z SLVSCP2E – JANUARY 2015 – REVISED MAY 2018 DRV10975 12-V, Three-Phase, Sensorless BLDC Motor Driver.

General Description

The DRV10975 device is a three-phase sensorless motor driver with integrated power MOSFETs, which can provide continuous drive current up to 1.5 A.

The device is specifically designed for cost-sensitive, lownoise, low-external-component-count applications.

The DRV10975 device uses a proprietary sensorless control scheme to provide continuous sinusoidal drive, which significantly reduces the pure tone acoustics that typically occur as a result of commutation.

Key Features

  • 1 Input Voltage Range: 6.5 to 18 V.
  • Total Driver H + L rDS(on): 250 mΩ.
  • Drive Current: 1.5-A Continuous Winding Current (2-A Peak).
  • Sensorless Proprietary Back Electromotive Force (BEMF) Control Scheme.
  • Continuous Sinusoidal 180° Commutation.
  • No External Sense Resistor Required.
  • For Flexibility User May Include External Sense Resistor to Monitor Power Delivered to Motor.
  • Flexible User Interface Options:.
  • I2C Interfa.
