A3982
Description (continued)
DMOS Stepper Motor Driver with Translator
fixed off-time, then to a slow decay for the remainder of the
off-time). This current decay control scheme results in reduced
audible motor noise, increased step accuracy, and reduced power
dissipation.
Internal synchronous rectification control circuitry is provided to
improve power dissipation during PWM operation.
Selection Guide
Internal circuit protection includes: thermal shutdown with
hysteresis, undervoltage lockout (UVLO), and crossover-current
protection. Special power-on sequencing is not required.
The A3982 is supplied in a 24-pin wide-body SOIC
(package LB) with internally-fused power ground leads for
enhanced thermal dissipation. It is lead (Pb) free, with 100%
matte tin plated leadframe.
