8bit Serial controlled bipolar stepping motor driver

Features

・BiCD process integrated monolithic IC.

・Capable of controlling one bipolar stepping motor.

・PWM controlled constant-current drive.

・Built-in serial-parallel convert circuit (8bit shift register)

・3-line (Data, Clock, Latch) serial output function for cascade connection

・Allows full, half step operation

・4 bit (16 steps) adjustable torque function (TRQ1,TRQ2,TRQ3,TRQ4).

・Low on-resistance MOSFET output stage.( Ron(D-S))

・High voltage and current (for specification, please refer to the absolute maximum ratings and operation

ranges).

・Built-in error detection circuits (Thermal shutdown (TSD), over current shutdown (ISD), and power on

reset(POR)).

・Built-in VCC regulator for internal use.

・Chopping frequency of a motor can be customized by external resistance and capacitor.
