Stmicroelectronics (ST) launched a new series of low power miniature motor drive, to pick up precision battery devices become smaller and more portable, and longer battery life.

Stmicroelectronics industrial and power conversion products division, general manager of Domenico Arrigo, said the new STSPIN single chip driver can simplify motor precision control design of new products, shorten the development cycle. Ultra-low power consumption will help extend the product life of batteries, let the designers for portable devices and action to increase the high additional value products motor function.

The new product size only 3 mm * 3 mm, is a very small single chip motor drive, assist in product design personnel provides a quick and light and friendly innovative products to the target market. The driver can save battery power, operating voltage as long as the lowest 1.8 V, the support power saving design, the standby current is less than 80 na, can meet the demand of motor in the zero power consumption during operation. In addition, this offered 1.3 very different drives the motor current, can be used for various applications, including robot positioning system, the printer motor, camera autofocus mechanism, the tooth brush motor or or injection pump.

This series of products including STSPIN220 stepper motor drives, STSPIN230 three-phase brushless motor (BLDC) motors drive and STSPIN240 double motor drive, including STSPIN240 single chip with two complete MOSFET bridge, can drive two brushless dc motors, drives and all have put together a comprehensive protection function, including the over-current protection, overheating protection and short circuit protection.
