General Description
The AMIS-30624 is a single-chip microstepping motordriver 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 I
C master. This significantly reduces system complexity.
The chip receives positioning instructions through the bus and subsequently drives the stator coils so the two-phase stepper motor
moves 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. 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 AMIS-30624 can easily be connected to an I
C bus where the I
C master can fetch specific status information
like actual position, error flags, etc. from each individual slave node.
An integrated sensorless 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 I2T100 technology, enabling both high voltage analog circuitry and digital functionality on the same chip.
The AMIS-30624 is fully compatible with the automotive voltage requirements.
