L6474 - Fully integrated microstepping motor driver

Description

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.

Features

  • Operating voltage: 8 - 45 V.
  • 7.0 A output peak current (3.0 A r. 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.
