Integrated 30-W Sensorless BLDC Motor Drive Retrofit Reference Design with 90- to 265-V AC Input(TIDA-01417)

The TIDA-01417 TI design provides a reference solution to drive 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. The design also combines a fully integrated and well protected single-chip, sensorless, sinusoidal brushless motor controller for low audible noise operation. The total solution is optimized with very small form factor and high efficiency which could be easily fit into motor.

Возможности

Reinforced isolated flyback AC/DC power supply providing 24V/36W output Very low standby power below 50mW 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 Ø64mm Fully protected system with short circuit, over current, blocked rotor protection
