A2918 Datasheet PDF - Allegro MicroSystems

The A2918SWH and A2918SWV motor drivers are designed to drive both windings of a bipolar stepper motor or bidirectionally control two dc motors. All bridges are capable of sustaining 45 V and include internal pulse-width modulation (PWM) control of the output current to 1.5 A.

FEATURES
■ ±1.5 A Continuous Output Current
■ 45 V Output Sustaining Voltage
■ Internal PWM Current Control
■ Low Output Saturation Voltage
■ Internal Clamp Diodes
■ Internal Thermal Shutdown Circuitry
■ Similar to Dual PBL3718 or Dual PBL3770
