STMicroelectronics Reveals World's Smallest Motor Drivers to Streamline Design and Boost Runtime of Battery-Powered Devices for the Internet of Things
(Thomson Reuters ONE) -
* World's smallest full-featured motor drivers simplify design and save space
in battery-powered and portable applications with unprecedented accuracy and
smoothness of motion
* Superior energy efficiency including zero-power mode with best-in-class
standby power consumption extends battery life
Geneva, July 6, 2016 - With the expansion of portable technology in everyday
life, new tiny, low-power electric-motor drivers from STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers across the spectrum of
electronics applications, are enabling sophisticated battery-powered equipment
to become smaller and more mobile with extended runtime.
Controlling the motors at the heart of devices like portable medical pumps and
drivers, personal wellness devices, portable point-of-sale devices, miniature
robots, surveillance equipment, precision tools, and portable printers requires
considerable engineering know-how. One of the biggest challenges is to combine
logic and power components in a single chip on tight space and power budgets.
ST has now gathered all of these ingredients together in its new line-up of tiny
single-chip motor drivers that meet the needs of the most demanding portable and
wearable applications. The combination of low power consumption, small form
factor, and outstanding performance of ST's new motor drivers is set to
contribute to the widespread adoption of battery-powered IoT devices.
Measuring just 3mm x 3mm, ST's new devices are 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
1.8V and support power-saving design with ultra-low, best-in-class standby
current of less than 80nA for a zero-power state when the motor is inactive. On
the other hand, they can supply up to 1.3A(rms) 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.
"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 low-power, low-voltage STSPIN motor drivers are in production now, in
3mm x 3mm QFN packages, priced from $0.75 for the STSPIN230 and STSPIN240, and
$0.95 for the STSPIN220, for orders of 1,000 pieces.
Further Technical Information:
The series currently comprises the STSPIN220 stepper-motor driver, STSPIN230 3-
phase brushless-motor (BLDC) driver, and STSPIN240 with two complete on-chip
MOSFET bridges for driving two brushed DC motors. Another device designed to
drive a single brushed DC motor with the current capability extended to
2.6A(rms )will go in production during Q3 2016. The power stage of each device
features efficient integrated MOSFETs that minimize energy loss and heat
dissipation. Despite their tiny size, there is no compromise in performance or
function. The STSPIN220 can drive stepper motors with position resolution of
256 microsteps per step, enabling extremely smooth motion and fine positional
accuracy.
In addition, all devices benefit from comprehensive built-in protection features
including over-current, over-temperature, and short-circuit protection. These
ensure ruggedness and reliability, even in harsh industrial environments,
without additional components thereby further reducing cost and complexity.
