DESCRIPTION
The APS12200, APS12210, and APS12230 are three-wire, planar
Hall-effect sensor integrated circuits (ICs). These devices were
developed in accordance with ISO 26262:2011 and support a
functional safety level of ASIL A (pending assessment).
This family of precision Hall-effect latch ICs feature extended
AEC-Q100 qualification and are ideal for high-temperature
operation up to 175°C junction temperatures. In addition,
the APS12200/10/30 include a number of features designed
specifically to maximize system robustness, such as reverse-
battery 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.
