APS13290 and APS13291: Precision Hall-Effect Latches for Consumer and Industrial Applications

Description

The APS13290 and APS13291 are three-wire, planar Hall-effect sensor integrated circuits (ICs) especially suited for operation over extended temperature ranges (up to 125°C).

This family of precision Hall-effect latch ICs are ideal for industrial and consumer applications and feature performance enhancements permitting high-temperature operation up to 175°C junction temperatures. In addition, the APS13290/1 include 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; a north pole of sufficient strength is necessary to turn the output off. The devices include on-board transient protection for all pins, permitting operation directly from a vehicle battery or regulator with supply voltages from 2.8 to 24 V.

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 UA is a three-pin ultramini SIP for through-hole mounting. Both packages are lead (Pb) free and RoHS compliant, with 100% matte-tin-plated leadframes.
