CLOCK-in controlled Bipolar Stepping Motor Driver

Features

・ BiCD process integrated monolithic IC.

・ Capable of controlling 1 bipolar stepping motor.

・ PWM controlled constant-current drive.

・ Allows full, half(a)(b), quarter, 1/8, 1/16, and 1/32 step operation.

・ Low on-resistance (High + Low side=0.49Ω(typ.)) MOSFET output stage.

・ Selectable Mixed Decay mode

・ High voltage and current (For specification, please refer to absolute maximum ratings and operation ranges)

・ Built-in error detection (TSD/ISD) signal output function

・ Built-in error detection circuits (Thermal shutdown (TSD), over-current shutdown (ISD), and under voltage lock out

(UVLO))

・ Built-in VCC regulator for internal circuit use.

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