DESCRIPTION
The APS11200 is a three-wire, planar Hall-effect sensor
integrated circuit (IC).This device was developed in accordance
with ISO 26262 and supports a functional safety level ofASILA.
This Hall-effect switch IC features extended AEC-Q100
qualification and is ideal for high-temperature operation up
to 175°C junction temperatures. In addition, the APS11200
includes 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. 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 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 SOT23W, surface-
mount 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.
