  • The L6470 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 on-chip current sensing circuitry suitable for non-dissipative current control and overcurrent protection. Thanks to a unique control system, a true 1/128 steps resolution is achieved. The digital control core can generate user defined motion profiles with acceleration, deceleration, speed or target position, easily programmed through a dedicated registers set. All commands and data registers, including those used to set analogue values (i.e. current control value, current protection trip point, deadtime, PWM frequency, etc.) are sent through a standard 5-Mbit/s SPI. A very rich set of protections (thermal, low bus voltage, overcurrent, motor stall) allows the design of a fully protected application, as required by the most demanding motor control applications.

    Key Features

    • Operating voltage: 8 - 45 V
    • 7.0 A out peak current (3.0 A r.m.s.)
    • Low RDS(on)Power MOSFETs
    • Programmable speed profile and positioning
    • Programmable power MOS slew rate
    • Up to 1/128 microstepping
    • Sensorless stall detection
    • SPI interface
    • Low quiescent and standby currents
    • Programmable non-dissipative overcurrent protection on high and low-side
    • Two-levels of overtemperature protection
