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, quarter step operation.

・Low on-resistance (High + Low side=0.8Ω(typ)) MOSFET

output stage.

・High efficiency motor current control mechanism (Advanced

Dynamic Mixed Decay)

・High voltage and current (For specification, please refer to absolute

maximum ratings and operation ranges)

・Error detection (TSD/ISD) signal output function

・Built-in error detection circuits (Thermal shutdown (TSD), over-current

shutdown (ISD), and power-on reset (POR))

・Built-in VCC regulator for internal circuit use.

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

and capacitor.
