STMicroelectronics has introduced a new line up of world’s smallest single-chip motor drivers for the portable and wearable applications. With the combination of low power consumption and small form factor, the ST’s new motor driver plans to contribute to the battery powered IoT device adoption.
The 3mm by 3mm motor drivers will focus on combining logic and power components in a single chip while taking care of power budgets and tight space. The drivers will operate from a supply voltage of 1.8V with the standby current of less than 80nA for a zero-power state. The drivers can also be used in a wide range of applications including robotic positioning systems, printer motors, camera-autofocus mechanisms, toothbrush motors or syringe pumps.
The existence of portable devices in everyday life is becoming more significant with the considerable increase in the use of well-developed battery-powered equipment with extended run-time that becomes smaller day by day.
“Our latest STSPIN single-chip devices are proven to simplify precision motor control and cut time to market for new products,” said Domenico Arrigo, General Manager Industrial and Power Conversion Division, STMicroelectronics. “The ultra-low power consumption extends runtime in battery-operated applications and enables designers to enhance portable and mobile devices with high-added-value motorized functions.”
ST’s new STSPIN motor devices are in production and are priced from $0.75 and $o.96 for order of 1,000 pieces.
