Overview

NCV70627 Micro-stepping Motor Driver Introduction The NCV70627 is a single−chip micro−stepping motor driver with position controller and control/diagnostic interface.
It is ready to build dedicated mechatronics solutions connected remotely with a LIN master.
The chip receives positioning instructions through the bus and subsequently drives the motor coils to the desired position.
The on−chip position controller is configurable (OTP or RAM) for different motor types, positioning ranges and parameters for speed, acceleration and deceleration.
The NCV70627 acts as a slave on the LIN bus and the master can fetch specific status information like actual position, error flags, etc.
from each individual slave node.
An integrated sensor−less step−loss detection prevents the positioner from loosing steps and stops the motor when running into stall.
This enables silent, yet accurate position calibrations during a referencing run and allows semi−closed loop operation when approaching the mechanical end−stops.
The chip is implemented in I3T50 technology, enabling both high voltage analog circuitry and digital functionality on the same chip.
The NCV70627 is fully compatible with the automotive voltage requirements.
Due to the technology, the device is especially suited for use in applications with fluctuating battery supplies.
