TIDA-01417

Design files

Overview

This reference design drives the low-voltage brushless DC (BLDC) motor with universal AC power supply input. The design has an onboard, reinforced isolated AC/DC switch power supply to convert the AC main input to isolated low-voltage DC output. It also combines a fully-integrated and well-protected single-chip, sensorless, sinusoidal brushless motor controller for low-audible noise operation. The desin is optimized with very small form factor and high efficiency which could be easily fit into motor.

Features
  • Reinforced isolated flyback AC/DC power supply providing 24-V/36-W output
  • Very low-standby power below 50 mW and high-efficiency AC/DC power supply giving a full load efficiency of 86%
  • Highly integrated and protected single-chip, sinusoidal brushless motor controller reduces external parts count eliminating the programming overhead of motor control
  • Small PCB form factor of Ø64 mm
  • Fully protected system with short circuit, over current, blocked rotor protection
