STMicroelectronics STSPIN motor drivers

Click2Contact

STMicroelectronics’ line of STSPIN single-chip motor drivers is said to meet the needs of the most demanding portable and wearable applications. Measuring just 3 x 3 mm, the devices are claimed to be the world’s smallest single-chip motor drivers integrating all the functionalities to enable product designers to deliver compact, lightweight and user-friendly innovations into their target markets.

Frugal with battery energy, the drivers operate from a supply voltage as low as 1.8 V and support power-saving design with ultralow standby current of less than 80 nA for a zero-power state when the motor is inactive. They can supply up to 1.3 Arms to drive the motor and can therefore be used in a wide range of applications, including robotic positioning systems, printer motors, camera-autofocus mechanisms, toothbrush motors and syringe pumps.

The single-chip devices are said to simplify precision motor control and cut time to market. The ultralow power consumption extends runtime in battery-operated applications and enables designers to enhance portable and mobile devices with high-added-value motorised functions. The combination of low power consumption, small form factor and high performance is expected to contribute to the widespread adoption of battery-powered IoT devices.
