AMIS-30622 I²C Micro-Stepping MotorDriver
● The AMIS−30622 is a single−chip micro−stepping 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 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.Micro−stepping 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−30622 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.
● The chip is implemented in I2T100 technology, enabling both high voltage analog circuitry and digital functionality on the same chip.
