TDK-Micronas’ HAL® 15xy Hall Effect Switches

With over six billion hall sensors shipped to the automotive and industrial market, TDK-Micronas leverages over 25 years of industry experience to supply best-in-class sensor and attenuator solutions. Their latest HAL® 15xy product family consists of the industry’s first compact, robust, safe, and power-friendly Hall switches that are ISO26262 compliant in SOT23 packaging.

The HAL 15xy Family of Hall Switches

HAL 15xy sensors are monolithic integrated circuits (Figure 1) capable of switching in response to magnetic fields. In comparison to its predecessor, the HAL 5xy, the HAL 15xy integrates a temperature-compensated Hall plate with active offset & comparator. HAL 15xy products are available with open-drain or current output. Additionally, the HAL 15xy line operates with improved lower supply current requirements, higher dynamic magnetic fields, lower jitter, and a wide supply voltage range. Most notably, HAL 15xy sensors are ISO26262 certified and AEC-100 qualified.

The HAL 15xy family of Hall switches is a comprehensive line of products that offers many variations in switching points and temperature coefficients to meet developer requirements. HAL 15xy products provide next-generation power, robustness, and safety performance in SOT23 & TO92-UA packaging. Equipped with new and advanced monitoring features, HAL 15xy switches offer a single point fault metric greater than 60%.
