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.
