On July 12, 2016 - for portable electronic technology popularization application in daily life, across multiple electronic application field, the world's leading supplier of semiconductor STMicroelectronics (STMicroelectronics, referred to as "ST; the New York stock exchange code: STM) launched a new series of low power miniature motor drive, let precision advanced battery power equipment become smaller and more portable, battery life is longer. Motor is a portable medical injection pump and drives, and personal fitness equipment, portable POS machine, miniature robot, security monitoring equipment, precision electronic equipment such as power tools, portable printers core components, motor control needs a lot of practical research and development related to electrical engineering knowledge and skills. In accordance with the requirements of the design size and power budget, on the single chip integration logic unit and power device, is one of the biggest challenges facing product designers. Now stmicroelectronics new series miniature single motor drive integrates all these functions, meet the most stringent portable and on the technical requirements of equipment. Low power consumption, small size, high performance, stmicroelectronics new motor drives will promote batteries iot are widely used in hardware. Stmicroelectronics only 3 mm x 3 mm size, the new products is the world's smallest single motor drive, and integrates product design staff for the target market to provide compact, lightweight, innovative products to use all the required functions.

A new drive to save battery power, working voltage is 1.8 V, support energy saving design, standby current industry in the lowest, less than 80 na, satisfy the requirement of the motor does not work when the state of zero power consumption. In addition, the driver can provide 1.3 very different drive current, thus can be used in the design of various applications, including robot localization system, printers, motor, camera autofocus mechanism, toothbrush or injection pump. Stmicroelectronics industrial and power conversion products division, general manager of Domenico Arrigo said: "it has been proved that our latest STSPIN monolithic driver can simplify the precision control of new products design and shorten the development cycle. Ultra-low power consumption helps to prolong the battery life of battery products, let the designers to give the portable and mobile products increase electric function with high added value." Stmicroelectronics low power consumption and low voltage STSPIN mass production of the new product is now in, using 3 mm x 3 mm QFN packages. Technical details: currently, this series of products including STSPIN220 stepper motor drives, STSPIN230 three phase brushless motor (BLDC) motors drive and STSPIN240 double motor drive, including STSPIN240 monolithic integrated two complete MOSFET bridge, can drive two brushless dc motors. In the third quarter of 2016 stmicroelectronics also plans to launch a brushless dc motor drive products, the expansion of output current into 2.6 very different. Every driver chip power level integrated energy-efficient MOSFET transistors, minimize the power loss and heat dissipation. Although the size is very small, but not sacrifice any performance and functionality. STSPIN220 stepper motor drives the positioning of the resolution of each step 256 micro step, make motor running very smooth, precise position. In addition, all drive integrated comprehensive protection function, including the over-current protection, overheating protection and short circuit protection. The protection function to ensure drive work stable and reliable, especially in harsh industrial environments, without having to increase external protection device, so as to further reduce the design cost and complexity.
