AMI Semiconductor (AMIS, Pocatello, ID), a leader in the design and manufacture of application-specific integrated circuits introduced its single–chip, local interconnect network (LIN) device. The AMIS-30621 is a new micro-stepping motor driver for remote and multiple axes positioning applications. The single–chip solution integrates bus connection, positioning electronics and a motor driver in a single SOP20 package.
The new AMIS-3062x family of micro-stepping motor driver products currently consists of two products: the AMIS–30621 with a LIN bus interface and the AMIS–30622 with a serial bus interface. Both versions are designed for small-positioning automotive applications such as headlamp leveling and swiveling, cruise control, and idle control. The devices can also be used in a wide range of industrial applications such as X, Y and Z tables; robots; climate control; and process control.
The AMIS-3062x product family features flexibility of motion parameters, such as maximum speed, acceleration and driving current; an on-chip position controller to work with different motor types, load conditions and positioning ranges; a hold current; low standby current; and optional stall detection. The AMIS-30621 and AMIS-30622 are currently available at $2.20 per unit in quantities of 10,000. For both products, evaluation boards are available on request.
