PHASE-in controlled Bipolar Stepping Motor Driver IC

Features

• Capable of controlling 1 bipolar stepping motor.

• BiCD process integrated monolithic IC.

• PWM controlled constant-current drive.

• Allows Full Step, Half Step and 1/4 Step excitations.

• Output stage low on resistance by a BiCD process

• 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. Therefore it's possible to operate only by a VM power supply.

• Chopping frequency of a motor can be customized by external resistance and condenser.

High-speed Chopping by more than 100 kHz is possible.

• Packages: HSOP28-P-0450-0.80
