The L6474PD is a fully integrated micro-stepping Motor Driver realized in analogue mixed signal technology, integrates a dual low RDS(ON)DMOS full bridge with all power switches equipped with an accurate on-chip current sensing circuitry suitable for non-dissipative current control and over-current protections. All data registers, including those used to set analogue values are sent through a standard 5Mbit/s SPI.
