TB6588FG

TB6588FG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB6588FG 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) 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) Weight: 0.79 g (typ.) 1 2008-4-25 Free Datasheet http://www.datasheet4u.com/ TB6588FG Pin Assignment VM1 U V CW_CCW EN N.C.
