Features

* I I I I I I I ± 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 Always order by complete part number: Part Number A2918SWH A29

Applications

* INFORMATION PWM Current Control V PHASE + I OUT 0
* The A2918SWH/V dual bridges are designed to drive both windings of a bipolar stepper motor. Output current is sensed and controlled independently in each bridge by an external sense resistor (RS), an internal comparator, and an internal m
