APS13295: Precision Hall-Effect Switch for Consumer and Industrial Applications


The APS13295 Hall-effect switch is a three-wire, planar Hall-effect sensor integrated circuit (IC) especially suited for operation over extended temperature ranges (up to 125°C).

This Hall-effect switch IC is ideal for industrial and consumer applications and features performance enhancements permitting high-temperature operation up to 175°C junction temperatures. In addition, the APS13295 includes a number of features designed specifically to maximize system robustness such as reverse-polarity protection, output current limiter, overvoltage, and EMC protection.

The single silicon chip includes: a voltage regulator, a Hall plate, small signal amplifier, chopper stabilization, Schmitt trigger, and a short-circuit-protected open-drain output. A south pole of sufficient strength turns the output on. Removal of the magnetic field—or a north pole—turns the output off. The devices include on-board transient protection for all pins, permitting operation directly from unregulated or regulated supplies from 2.8 to 24 V.

Two package styles provide a choice of through-hole or surface mounting. Package type LH is a modified SOT23W, surfacemount package, while UA is a three-lead ultra-mini SIP for through-hole mounting. Both packages are lead (Pb) free and RoHs compliant with 100% matte-tin leadframe plating.
