Compare and Select (Reference Only)

  • Two full H-bridges = four half H-bridges. That means you can drive four solenoids, two DC motors bi-directionally
  • Stepper Guide

PWM DC Motor Driver (or stepper) / 1x H-Bridge

  • Ave. = Ave. / Current DC / Repeative / Continuous pulse
Type Voltage Ave. Peak / Single pulse Other Features Alternative
L9110 / HG7881 2.5V-12V - 0.8A - -
DRV8837 ~11V - 1.8A - -
