22-mm Diameter and Thermally Enhanced Three-Phase BLDC Motor Driver Reference Design

TIDA-01619

Design files

Overview

The TIDA-01619 provides a three-phase brushless DC (BLDC) motor driver solution for systems that have operating range from 4.4 V to 18 V.

This design features the DRV10974 motor driver with the ability to add MCU for closed loop speed control. The DRV10974 offers sensorless commutation with no need of hall sensors, only 6 external passive components allow for a low-cost solution, and an 180° sinusoidal commutation system allows optimal efficiency and low acoustics.

This reference design provides guidelines in 22-mm diameter board design and thermal enhancement with a double-layer layout and 2-oz copper thickness.

Features
  • Thermally Enhanced: 2 layers and 2 oz copper thickness
  • Small Form Factor: 22 mm diameter
  • Low acoustics
  • Ability to add MCU for closed loop speed control
  • Fully protected realized by on-chip protection from 10974

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
