Micropower Vertical and Planar Hall-Effect Switches

The APS11700/760 family of micropower Hall-effect switches adds automatic power management to Allegro’s APS11000/060 family of Hall-effect switches, enabling average supply current as low as 6µA. They are rugged enough for operation from batteries or unregulated supplies in harsh automotive and industrial environments. The power management happens in the background and is transparent to the host system, making them a drop-in upgrade for existing Hall-effect switches or a solid-state replacement for mechanical microswitches or reed switches. The APS11760 devices feature a vertical Hall-effect sensing element that is sensitive to magnetic flux parallel to the face of the IC package, mimicking the in-plane sensitivity of common reed switches.

These ICs are qualified to AEC-Q100 Grade 0. They can tolerate up to 40V and junction temperature up to 165°C. In addition, they are internally protected against over-voltage, reverse-battery, load-dump, output short-circuits, human-body-model ESD up to ±11kV, and other common automotive EMC conditions.

APS11700/760 devices come preconfigured with your choice of magnetic sensitivity, thresholds, and polarity. There is also a choice of active-high or active-low output for ease of integration into electronic subsystems.

Two package styles provide a choice of through-hole or surface mounting. Package type LH is a modified 3-pin SOT23W surface-mount package, while package type UA is a 3-pin ultra mini SIP for through-hole mounting. Both packages are lead (Pb) free, with 100% matte-tin-plated leadframes.
