Product Overview

L6470PD 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 nondissipative current control and overcurrent protection. Due 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.
  • Operating voltage range from 8 to 45V
  • 7.0A out peak current (3.0A r.m.s.)
  • Low RDS(on) power MOSFETs
  • Programmable speed profile and positioning
  • Programmable power MOS slew rate
  • Sensorless stall detection
  • Low quiescent and standby currents
  • Programmable non-dissipative overcurrent protection on high and low-side
  • Two-levels of overtemperature protection
  • Available in 36 pin PowerSOIC package
