Ultra-low Power Omnipolar Hall Effect Sensors from Diodes Incorporated Deliver Market-Leading Stability Over Wide Operating Range
Business Wire 27-Nov-2018 10:00 AM
Diodes Incorporated (NASDAQ:DIOD), a leading global manufacturer and
supplier of high-quality application specific standard products within
the broad discrete, logic, analog and mixed-signal semiconductor
markets, today announced the AH1911 and AH1921 digital Hall Effect
sensors, which combine market-leading stable operating and release
points (BOP and BRP) with ultra-low power
operation. The 3rd generation devices will respond to either
polarity of magnetic field and feature a ‘hibernating clock' system to
reduce average current consumption to 1.6µA at 3V supply.
A wide operating voltage range of 1.6V to 5.5V enables the parts to be
used with a variety of system voltages. Operating and release points for
the magnetic switch are tightly controlled over temperature and supply
voltage thanks to its advanced stabilizing technique, delivering
accurate and repeatable performance. Flux density switching points are
typically ±60 Gauss (6mT) to operate and ±45 Gauss (4.5mT) to release.
The AH1911 and AH1921 are ideal for battery-powered devices where its
ultra-low power consumption and wider operating voltage range promote
extended battery life. Typical applications include medical and consumer
products, tamper detection for e-meters, smoke detectors, IoT devices
and general level/proximity detection.
Available in the industry-standard three-pin SC59 package, the AH1911
and AH1921 feature push-pull and open-drain outputs, respectively. Both
are specified to operate over the -40°C to +85°C temperature range and
have a high ESD rating of 6kV (Human Body Model).
"These sensors, with their stable BOP/BRP and
ultra-low power consumption, provide market-leading performance at the
best cost/performance ratio," said Charles Kuo, worldwide sensor
marketing manager for Diodes Incorporated. Further information is
