Omnipolar Hall-effect switches from Diodes meet robust automotive environments

Omnipolar Hall-effect switches from Diodes are fully certified for automotive applications and qualified to AEC-Q100 Grade 0. Typical applications include position and proximity sensing, open and close detection, level detection and flow metering. The AH356xQ switches have a wide operating voltage range of 3.0 to 28V with a 8kV HBM ESD rating.

The switched are certified to meet environmental, quality and regulatory demands in the automotive industry. They have been designed to meet AEC-Q100 Grade 0, meaning they can operate across an extended ambient temperature range of -40 to +150 degrees C. Other features include input supply reverse polarity and over-voltage protection, output over-voltage and over-current protection.

The AH356xQ Hall-effect switches can be used for automotive proximity and level detection applications. Three versions are available, with different tight magnetic switching thresholds. All offer high threshold stability and low temperature drift, says Diodes. All of the devices in the AH356xQ series feature active-low, open-drain outputs and offer fast power-up (10 micro seconds) and response times (3.75 micro seconds), making them suitable for time-critical applications in protection and fault detection.

The AH356xQ series is available in SOT23 (tape-and-reel) and SIP-3 options.

Diodes manufactures and supplies application specific standard products (ASSPs) within the broad discrete, logic, analogue and mixed-signal semiconductor markets and for consumer electronics, computing, communications, industrial, and automotive markets. Its product portfolio includes diodes, rectifiers, transistors, MOSFETs, protection devices, function-specific arrays, single gate logic, amplifiers and comparators, Hall-effect and temperature sensors, power management devices, including LED drivers, AC/DC converters and controllers, DC/DC switching and linear voltage regulators, and voltage references along with special function devices, such as USB power switches, load switches, voltage supervisors, and motor controllers. Diodes also has timing, connectivity, switching, and signal integrity solutions for high-speed signals.
