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)
