LMD18201  
3A, 55V H-Bridge  
n TTL and CMOS compatible inputs  
n No “shoot-through” current

n Thermal shutdown (outputs off) at 170˚C  
n Internal clamp diodes  
General Description  
The LMD18201 is a 3A H-Bridge designed for motion control  
applications. The device is built using a multi-technology pro-  
cess which combines bipolar and CMOS control circuitry  
with DMOS power devices on the same monolithic structure.  
The H-Bridge configuration is ideal for driving DC and step-  
per motors. The LMD18201 accommodates peak output cur-  
rents up to 6A. Current sensing can be achieved via a small  
sense resistor connected in series with the power ground  
lead. For current sensing without disturbing the path of cur-  
rent to the load, the LMD18200 is recommended.  
n Shorted load protection  
n Internal charge pump with external bootstrap capability  
Applications  
n DC and stepper motor drives  
n Position and velocity servomechanisms  
n Factory automation robots  
n Numerically controlled machinery  
n Computer printers and plotters  
Features  
n Delivers up to 3A continuous output  
n Operates at supply voltages up to 55V  
n Low RDS(ON) typically 0.33per switch
