BiCD Constant-Current Two-Phase Bipolar Stepping Motor Driver IC

Features

• Bipolar stepping motor driver

• PWM constant-current drive

• Provides phase-A and phase-B enable inputs to allow 2-phase and 1-2-phase excitation.

• BiCD process: Uses DMOS FETs as output power transistors.

• High voltage and current: 40 V/1.8 A

• Thermal shutdown (TSD), over-current shutdown (ISD), and power-on-resets (PORs) for

VMR and VCCR

• Package: Heat-sink Small Outline Package (HSOP28-P-0450-0.80)
