PHASE-in controlled Bipolar Stepping Motor Driver

Features

・BiCD process integrated monolithic IC.

・PWM controlled constant-current drive.

・Allows full, half, quarter step operation.

・Low on-resistance (High + Low side = 0.49 Ω (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)

・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 resistor and capacitor.
