The AH356xQ series of omnipolar hall-effect switches by Diodes Incorporated is engineered for automotive applications. Among typical applications, there are position and proximity sensing, open/close detection, level detection and flow metering.
The new three devices offer a combination of performance and robustness that meets environmental, quality and regulatory standards in the automotive industry. Thanks to their AEC-Q100 Grade 0 qualification, they can operate across a temperature range from -40°C to +150°C. They have a wide operating voltage from 3V to 28V with 8kV HBM ESD rating. These switches are protected from overvoltage as well as output overvoltage and overcurrent, and also feature supply reverse polarity.
The AH356xQ series are available with different tight magnetic switching thresholds that include high threshold stability and low temperature drift. They are perfect for time-critical applications in protection and fault detection as they feature active-low, open-drain outputs, and give fast power-up (10µs) and response times (3.75µs).
Available in SOT23 (tape-and-reel) and SIP-3 (‘ammo’ or bulk).
