Hall Effect Latch For High Temperature Operation

These Hall-effect Latches A1225, A1227 A1229 are extremely temperature-stable and stress resistant Sensor ICs especially suited for operation over extended temperature ranges to 150°C. Superior hightemperature 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 element. Additionally, internal compensation provides magnetic switchpoints 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 three basic devices (A1225, A1227 and A1229) are identical except for magnetic switchpoints. By Allegro MicroSystems, Inc.
