DMOS Microstepping Driver with Translator  
Description (continued)  
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.  
lockout (UVLO), and crossover-current protection. Special power-  
on sequencing is not required.  
The A4983 is supplied in a 5 mm × 5 mm × 0.90 nominal surface  
mount QFN package with exposed thermal pad (suffix ET). The  
Internal synchronous rectification control circuitry is provided to  
improve power dissipation during PWM operation. Internal circuit

package is lead (Pb) free (suffix –T), with 100% matte tin plated  
leadframe.
