3-Phase Full-Wave Sensorless Controller for Brushless DC Motors

TB6537P/F is a 3-phase full-wave sensorless controller for

brushless DC motors. It is capable of controlling voltage by PWM

signal input. When combined with various drive circuits it can be

used for various types of motors.

Features

· 3-phase full-wave sensorless drive

· PWM control (PWM signal is supplied from external sources.)

· Turn-on signal output current: 20 mA

· Overcurrent protection function

· Forward/reverse modes

· Lead angle control function (0, 7.5, 15 and 30 degrees)

· Built-in lap turn-on function

· Two types of PWM output (upper PWM and upper/lower

alternate PWM)
