Preliminary Product Information
Dual Full-Bridge Stepper Motor Driver
General Description
The AT5519 motor driver is designed to drive both
winding of a bipolar stepper motor or bi-
directionally control two DC motor. An internal
PWM controls the output current to 750mA with
peak startup current up to 1A. Two logic-level
inputs select output current limits of 0, 33, 67, or
100% of the maximum level. A PHASE input to
each bridge determines load current direction. A
thermal protection circuitry disables the outputs if
the chip temperature exceeds safe operating limits.
Aimtron reserves the right without notice to change this circuitry and specifications.
