PHASE-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=0.49Ω(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 resistance and condenser.

?Multi package lineup
