AMI Semiconductor Launches Stepper Motor Controller ICs with Sensorless Stall Detection; LIN and Serial Interface ICs Improve Reliability and Reduce Component Count, Cost and Complexity of Automotive and Industrial Motion Control Applications.POCATELLO, Idaho Pocatello (IPA: [po kə tɛ lo]) is the county seat and largest city of Bannock CountyGR6 -- AMI Semiconductor AMI Semiconductor is a company engaged the design and manufacture of customer specific integrated circuit solutions, including solutions for the automotive, medical and industrial markets. Among its products are products that integrate processing of analog and digital signals. (Nasdaq:AMIS A·mis , Kingsley 1922-1995. British writer best known for his novels, including Lucky Jim (1954) and Jake's Thing (1978). ), a designer and manufacturer of state-of-the-art integrated mixed-signal and structured digital products for the automotive, medical and industrial markets, has expanded its family of single-chip stepper motor A motor that rotates in small, fixed increments and is used to control the movement of the access arm on a disk drive. Contrast with voice coil. (hardware) stepper motor driver and controller ICs with two new devices that incorporate sensorless stall detection. The new ICs will improve reliability and reduce component count, board space, cost, and development time in a wide variety of automotive and industrial motion control applications. The new AMIS-30623 and AMIS-30624 ICs are designed for remote and multiple axes positioning applications and offer LIN and serial (I2C I2C Inter-Integrated Circuit I2C Intelligent Interface Controller I2C Intelligent Controller ) interface connectivity respectively. Sensorless stall detection functionality allows designers to implement silent yet accurate position calibration and semi-closed loop operation when approaching mechanical end stops. The integrated 'Motion Qualification Mode' helps application developers to select a robust set of motion parameters such as torque and acceleration-deceleration profile. As a result, noise and vibration at end-stops can be eliminated and motion control accuracy and reliability improved without the need for optical encoders, position sensors or software algorithms. By offering a dedicated LIN interface, the AMIS-30623 will suit mechatronics (MECHAnics elecTRONICS) The combination of mechanical and electronic systems. Embracing robotics, industrial control systems and human interfaces in numerous disciplines, mechatronics is a major step beyond "electromechanical," in which only electricity is required. solutions that are connected remotely to a LIN master. The dedicated serial interface provided with the AMIS-30624 makes this device ideal for applications in which the motor controller IC is a peripheral device See peripheral. peripheral device - peripheral located next to a host microcontroller on a single PCB PCB: see polychlorinated biphenyl.

Target applications for the new devices will include headlamp leveling and swiveling, automotive HVAC (Heating Ventilation Air Conditioning) In the home or small office with a handful of computers, HVAC is more for human comfort than the machines. In large datacenters, a humidity-free room with a steady, cool temperature is essential for the trouble-free designs, surveillance camera control, professional lighting equipment, industrial 'X,Y,Z' tables, and manufacturing robots. Both the AMIS-30623 and AMIS-30624 will operate at temperatures from -40(degree)C to 125(degree)C and can deliver programmable peak currents of up to 800mA. The on-chip position controller is configurable for different motor types, positioning ranges and parameters such as speed, acceleration and deceleration deceleration /de·cel·er·a·tion/ (de-sel?er-a´shun) decrease in rate or speed. early deceleration . Each device also incorporates a hold current feature, while a power down supply current of under 100uA ensures minimum power consumption in standby mode. "The trend for automotive and industrial motion control applications is towards reduced component counts, smaller board space requirements and lower cost," said Bart De Cock, product manager of AMI Semiconductor's motor control product line. "These new devices with integrated stall detection directly address these trends by helping engineers to eliminate additional components and design complexity." Based on AMI Semiconductor's advanced mixed-signal semiconductor processes, the AMIS-30623 and AMIS-30624 are available in a choice of SOIC-20 or NQFP-32 packaging. Pricing is in the region of $4.40 (US) per part for orders in excess of 10,000 pieces.
