All-pole Hall effect switches for automotive applications

     Diodes introduces the market leading AH356xQ series of fully certified all-pole Hall switches for automotive applications, which also meet AEC-Q100 Class 0 standards. Common applications for these rugged Hall-effect switches include position and proximity sensing, open and closed circuit detection, level detection, and flow metering, with a wide operating voltage range from 3V to 28V and an excellent 8kV HBM ESD rating.

     The AH356xQ series is fully certified to not only meet the environmental, quality and regulatory requirements of the automotive industry, but also comply with AEC-Q100 level 0 standards, so it can operate in a wide ambient temperature range between -40°C and +150°C. Other features include input power supply reverse polarity and overvoltage protection, and output overvoltage and overcurrent protection. Packages such as SOT23 (tape and reel) and SIP-3 (folded (ammo) or bulk) are available

     "These robust, high-voltage all-pole Hall-effect switches meet automotive industry specifications and are ideal for automotive proximity and level detection applications," said Simon Ramsdale, Diodes Global Automotive IC Marketing Manager. "Since they are Class 0 compliant, they are both efficient and robust."

     The AH356xQ series offers three devices with a wide range of tight magnetic switching thresholds, all with high threshold stability and low temperature drift. All units in the AH356xQ series feature a low-state effective drain open output with fast power-on and response times (10µs and 3.75µs, respectively), making them particularly suitable for time-critical applications in protection and fault detection.
