A3980  
Automotive DMOS Microstepping Driver with Translator  
Features and Benefits  
Description  
Typical application up to ±1 A, 35 V output rating  
Low RDS(ON) outputs, 0.67 Ω source, 0.54 Ω sink typical  
Automatic current decay mode detection/selection  
3.0 V to 5.5 V logic supply voltage range  
Mixed, fast, and slow current decay modes  
Synchronous rectification for low power dissipation  
Internal OVLO, UVLO, and thermal shutdown circuitry  
Crossover current protection  
The A3980 is a complete microstepping motor driver with  
built-in translator for easy operation. It is designed to operate  
bipolar stepper motors in full-, half-, eighth-, and sixteenth-  
step modes, at up to 35 V and ±1 A. The A3980 includes a  
fixedoff-timecurrentregulatorwhichhastheabilitytooperate  
in slow, fast, or mixed decay modes. This results in reduced  
audible motor noise, increased step accuracy, and reduced  
power dissipation.  
Short to supply/ground and short/low load current  
diagnostics  
The translator is the key to the easy implementation of the  
A3980. Simply inputting one pulse on the step input drives  
the motor one microstep. There are no phase sequence tables,  
highfrequencycontrollines,orcomplexinterfacestoprogram.  
The A3980 interface is an ideal fit for applications where a  
complex μP is unavailable or overburdened.  
Package: 28 pin TSSOP with exposed  
thermal pad (suffix LP)  
Internalsynchronousrectificationcontrolcircuitryisprovided  
to improve power dissipation during PWM operation.  
Internal circuit protection includes: thermal shutdown with  
hysteresis,overvoltagelockout(OVLO),undervoltagelockout  
(UVLO), and crossover current protection. Special power-up  
sequencingisnotrequired.Inaddition,twodiagnosticfaultflags  
provide indication of shorts or opens on the motor windings.  
The A3980 is supplied in a low-profile (1.1 mm) 28L TSSOP  
with exposed thermal pad. This device is available also in a  
lead-free version (leadframe plating 100% matte tin).
