Description  
Tape and reel  
Tube  
The L6472, realized in analog mixed signal  
technology, is an advanced fully integrated  
solution suitable for driving two-phase bipolar  
stepper motors with microstepping. It integrates a  
dual low RDS(on) DMOS full bridge with all of the  
power switches equipped with an accurate on-  
chip current sensing circuitry suitable for non-  
dissipative current control and overcurrent  
protection. Thanks to a new current control, a  
1/16 microstepping is achieved through an  
adaptive decay mode which outperforms  
traditional implementations. The digital control  
core can generate user defined motion profiles  
with acceleration, deceleration, speed or target  
position, easily programmed through a dedicated  
register set.
