  • The L6474 device, 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, deadtime, etc.) are sent through a standard 5 Mbit/s SPI.
    A very rich set of protections (thermal, low bus voltage, overcurrent) makes the L6474 device “bullet proof” as required by the most demanding motor control applications.

    Key Features

    • Operating voltage: 8 - 45 V
    • 7.0 A output peak current (3.0 Ar.m.s.)
    • Low RDS(on)power MOSFETs
    • Programmable power MOS slew rate
    • Up to 1/16 microstepping
    • Current control with adaptive decay
    • Non-dissipative current sensing
    • SPI interface
    • Low quiescent and standby currents
    • Programmable non-dissipative overcurrent protection on all power MOS
    • Two-level overtemperature protection
