I2C Micro-stepping Motor
Driver
INTRODUCTION
The AMIS30624/NCV70624 is a singlechip microstepping
motor driver with a position controller and control/diagnostic
interface. It is ready to build intelligent peripheral systems where up to
32 drivers can be connected to one I2C master. This significantly
reduces system complexity.
The chip receives positioning instructions through the bus and
subsequently drives the stator coils so the twophase stepper motor
moves to the desired position. The onchip position controller is
configurable (OTP or RAM) for different motor types, positioning
ranges and parameters for speed, acceleration and deceleration.
Microstepping allows silent motor operation and increased
positioning resolution. The advanced motion qualification mode
enables verification of the complete mechanical system in function of
the selected motion parameters. The AMIS30624/NCV70624 can
easily be connected to an I2C bus where the I2C master can fetch
specific status information like actual position, error flags, etc. from
each individual slave node.
An integrated sensorless steploss 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 semiclosed loop operation when approaching the
mechanical endstops.
The chip is implemented in I2T100 technology, enabling both high
voltage analog circuitry and digital functionality on the same chip.
The NCV70624 is fully compatible with the automotive voltage
requirements.

APPLICATIONS
The AMIS30624/NCV70624 is ideally suited for small
positioning applications. Target markets include:
automotive (headlamp alignment, HVAC, idle control,
cruise control), industrial equipment (lighting, fluid control,
labeling, process control, XYZ tables, robots) and building
automation (HVAC, surveillance, satellite dish, renewable
energy systems). Suitable applications typically have
multiple axes or require mechatronic solutions with the
driver chip mounted directly on the motor.
