ATS635LSE and ATS636LSE

Programmable Back Biased Hall-Effect

Switch with TPOS Functionality

The ATS635LSE and ATS636LSE programmable, true power-on state

(TPOS), sensors are an optimized Hall-effect IC and magnet combination

that switch in response to magnetic signals created by ferrous targets in

gear-tooth sensing and proximity applications.

PACKAGE DIAGRAM

The devices are externally programmable.

A wide range of

programmability is available on the magnetic operate point (B_OP) while the

hysteresis remains fixed. This advanced feature allows for optimization of

the sensor switch point 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 sensor system is ideal for use in gathering speed or position

information using gear-tooth-based configurations, or for proximity sensing

with ferrous targets.

The ATS635LSE switches HIGH in the presence of a ferrous target or

tooth and switches LOW in the presence of a target valley, window, or

when the ferrous target is removed. The ATS636LSE has the opposite

polarity and switches LOW in the presence of a ferrous target or tooth and

switches HIGH in the presence of a target valley, window, or when the

ferrous target is removed.

These devices are available in lead (Pb) free versions, with 100%

matte tin leadframe plating.
