L6472
Description
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.
