3-Phase Full-Wave PWM Driver for Sensorless DC Motors
The TB6588FG is a three-phase full-wave PWM driver for
sensorless brushless DC (BLDC) motors. It controls rotation speed
by changing the PWM duty cycle, based on the voltage of an
analog control input.
Features
Sensorless drive in three-phase full-wave mode
PWM chopper control
Controls the PWM duty cycle, based on an analog input
(7-bit ADC)
Weight: 0.79 g (typ.)
Output current: IOUT = 1.5 A typ. (2.5 A max)
Power supply: VM = 7 to 42 V (50 V max)
Overcurrent protection
Forward and reverse rotation
Lead angle control (0°, 7.5°, 15°, 30°)
Overlapping commutation
Rotation speed detecting signal
DC excitation mode to improve starting characteristics
Adjustable DC excitation time and forced commutation time for a startup operation
Forced commutation frequency control: fosc/(6 × 216), fosc/(6 × 217), fosc/(6 × 218), fosc/(6 × 219)
