STMicroelectronics L6474 easySPIN Microstepping Motor Driver Datasheet
The L6474 is a fully integrated microstepping motor driver realized in analog mixed signal technology. It integrates a dual low RDSon DMOS full bridge with all power switches equipped with an accurate on-chip current sensing circuitry suitable for non dissipative current control and overcurrent protections. The device supports up to 1/16 microstepping through an adaptive decay mode which outperforms traditional implementations.
