Ultra-Low Power Omnipolar Hall Effect Sensors from Diodes Incorporated Deliver Market-Leading Stability Over Wide Operating Range

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 introduced the AH1911/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 use 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 part 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 due to advanced stabilizing techniques for accurate and repeatable performance. Flux density switching points are typically ±60 Gauss (6mT) to operate and ±45 Gauss (4.5mT) to release.

The AH1911/21 is ideal for battery-powered devices where the low power consumption and wider operating voltage range help to extend 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 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 available at www.diodes.com.
