L6474
easySPIN - fully integrated microstepping motor driver-
アクティブ
The L6474, realized in analog 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 overcurrent protections. Thanks to a new current control, a 1/16 microstepping is achieved through an adaptive decay mode which outperforms traditional implementations.
All data registers, including those used to set analogue values (i.e. current control value, current protection trip point, dead time, etc.) are sent through a standard 5 Mbit/s SPI.
A very rich set of protections (thermal, low bus voltage, overcurrent) makes the L6474 “bullet proof” as required by the most demanding motor control applications.
