A3983
Description (continued)
DMOS Microstepping Driver with Translator
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. Internal circuit
protection includes: thermal shutdown with hysteresis, undervoltage

lockout (UVLO), and crossover-current protection. Special power-
on sequencing is not required.
The A3983 is supplied in a low-profile (1.2 mm maximum height),
24-pin TSSOP with exposed thermal pad (suffix LP). It is lead (Pb)
free, with 100% matte tin leadframe plating.
