L6472 Overview
The L6472 device, 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 onchip current sensing circuitry suitable for non dissipative current control and overcurrent protection. Thanks to a new current...
