Description
The ATS635LSE and ATS636LSE programmable, true
power-on state (TPOS), devices are optimized Hall-effect IC
and rare-earth pellet combinations that switch in response to
magnetic signals created by ferromagnetic targets in gear-tooth
sensing and proximity applications.
The devices are externally programmable. A wide range of
programmability is available on the magnetic operate point
(BOP) while the hysteresis remains fixed. This advanced
feature allows for optimization of the circuit switchpoint and
can drastically reduce the effects of mechanical placement
tolerances found in production environments .
A proprietary dynamic offset cancellation technique, with
an internal high-frequency clock, reduces the residual offset
voltage, which is normally caused by device overmolding,
temperature dependencies, and thermal stress. Having the Hall
elementandamplifierinasinglechipminimizesmanyproblems
normally associated with low-level analog signals.
This device is ideal for use in gathering speed or position
information using gear-tooth-based configurations, or for
proximity sensing with ferromagnetic targets.
The ATS635LSE switches high in the presence of a
ferromagnetic target or tooth and switches low in the presence of
635LSE-DS, Rev. 4
