TA8435H/HQ
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8435H/HQ
PWM CHOPPER-TYPE BIPOLAR STEPPING MOTOR DRIVER.
The TA8435H/HQ is a PWM chopper-type sinusoidal micro-step
bipolar stepping motor driver.
Sinusoidal micro-step operation is achieved using only a clock
signal input by means of built-in hardware.
