ON Semiconductor collaborates with Stegia to bring ultra small smart motor solutions to market
June 29, 2011 // Paul Buckley
ON Semiconductor and leading Nordic motor supplier Stegia have announced that ON Semiconductor’s AMIS-30624 2-phase stepper motor driver, with built-in position controller and I2C serial interfacing, has been incorporated into Stegia’s stepper motor product line. This enables the creation of highly compact motor systems with next generation functionality.
Commands for controlling the acceleration, deceleration, position and speed of the motor are carried out through the AMIS-30624s I2C interface in microsteps. This results in silent motor operation, as well as enhancing positioning resolution. A stream of valuable diagnostic data can also be sent back to the motor systems host controller via the I2C interface.
Utilisation of an I2C interface limits the amount of cabling to the motor, thereby reducing bill of materials costs and lowering the systems overall electromagnetic radiation level. It is possible to connect up to 32 drivers to one I2C master, so that system complexity can be kept to a minimum.
The AMIS-30624 has a peak current of 800 mA and is fully compatible with automotive voltage requirements, with supply voltages of 8 V to 29 V being supported. Its operational temperature range of -40 to 125 C allows it to be employed in automotive and industrial environments.
This highly integrated device is optimised for use in any electromechanical system that requires precise, high reliability positional control, such as damper control systems for building automation, remote access control for hotel rooms, remote tuning of cellular base stations, vehicle headlamp positioning systems, and surveillance systems (pan-tilt-zoom cameras), as well as automotive, residential, and commercial comfort systems.
