STMicroelectronics has revealed a new lineup of tiny single-chip motor drivers that meet the needs of the most demanding portable and wearable applications. Measuring just 3 x 3 mm, they are claimed to be the world’s smallest, and operate from a supply voltage as low as 1,8 V with standby current of less than 80 nA for a zero-power state when the motor is inactive. On the other hand, they can supply up to 1,3 Arms to drive the motor and can therefore be used in a wide range of applications that include robotic positioning systems, printer motors, camera autofocus mechanisms, toothbrush motors or syringe pumps. The new STSPIN motor drivers are in production now, in 3 x 3 mm QFN packages.
