ATS635LSE and ATS636LSE: Programmable Back Biased Hall-Effect Switch with TPOS Functionality

The ATS635LSE is no longer in production. The device should not be purchased for new design applications. Samples are no longer available. Date of status change: January 30, 2012. Its product information has been removed from the datasheet.

The ATS636LSE is no longer in production. The device should not be purchased for new design applications. Samples are no longer available. Date of status change: December 1, 2015.

Recommended Substitutions: For existing customer transition, and for new customers or new applications, refer to the ATS128LSETN-T.

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 element and amplifier in a single chip minimizes many problems 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 a target valley, window, or when the ferromagnetic target is removed. The ATS636LSE has the opposite polarity and switches low in the presence of a ferromagnetic target or tooth and switches high in the presence of a target valley, window, or when the ferromagnetic target is removed.
