A4986  
DMOS Dual Full-Bridge PWM Motor Driver  
with Overcurrent Protection  
Features and Benefits  
Low RDS(ON) outputs  
Description  
The A4986 is a dual DMOS full-bridge stepper motor driver  
Internal mixed current decay mode  
Synchronous rectification for low power dissipation  
Internal UVLO  
withparallelinputcommunicationandovercurrentprotection.  
Each full-bridge output is rated up to 35 V and ±2 A.  
The A4986 includes fixed off-time pulse width modulation  
(PWM) current regulators, along with 2- bit nonlinear DACs  
(digital-to-analog converters) that allow stepper motors to be  
controlled in full, half, and quarter steps. The PWM current  
regulator uses the Allegro® patented mixed decay mode for  
reduced audible motor noise, increased step accuracy, and  
reduced power dissipation.  
Crossover-current protection  
3.3 and 5 V compatible logic supply  
Thin profile QFN and TSSOP packages  
Thermal shutdown circuitry  
Short-to-ground protection  
Shorted load protection  
Low current Sleep mode, < 10 μA  
Internalsynchronousrectificationcontrolcircuitryisprovided  
to improve power dissipation during PWM operation.  
The outputs are protected from shorted load and short-to-  
groundevents,whichprotectthedriverandassociatedcircuitry  
from thermal damage or flare-ups. Other protection features  
includethermalshutdownwithhysteresis,undervoltagelockout  
(UVLO) and crossover current protection. Special power-up  
sequencing is not required.  
Package:  
The A4986 is supplied in a 24-pin TSSOP (LP) with exposed  
thermal pad for enhanced thermal performance. It has a  
0.65 pitch and an overall package height of 1.2 mm. It is lead  
(Pb) free, with 100% matte tin leadframe plating.
