Features & Applications

The L6470H is an advanced fully integrated microstepping motor driver with motion engine and SPI; which is suitable for driving two-phase bipolar stepper motors.

It integrates a dual low RDS(on) DMOS full bridge with power switch equipped with an accurate on-chip current sensing circuit.

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

Applications:

  • Bipolar stepper motors
  • Industrial
  • Automotive
