Hall Effect Latches For High Temperature Operation

These Hall-effect Latches are extremely temperature-stable and stress- resistant Sensors especially suited for operation over extended temperature ranges to +150. Superior high-temperature performance is made possible through a novel Schmitt Trigger circuit that maintains operate and release point symmetry by compensating for temperature changes in the Hall ele- ment. Additionally, internal compensation provides magnetic Switch points that become more sensitive with temperature, hence offsetting the usual degradation of the magnetic field with temperature. The symmetry capability makes these devices ideal for use in pulse-counting applications where duty cycle is an important parameter. The four basic devices ( A3185 A3187 A3188 and A3189 ) are identical except for magnetic Switch points. By Allegro MicroSystems, Inc.
