65025 HIGH RELIABILITY HALL EFFECT SENSOR, LATCHING OUTPUT OPTOELECTRONIC PRODUCTS DIVISION 07/22/2009 Features: Applications: • • • • • • • • • • • Wide operating temperature range -55°C to +200°C High magnetic sensitivity Low current CMOS Technology Wide operating voltage range 3.5 to 20 V Chopper stabilized amplifier minimizes amplifier offset resulting in improved temperature stability Solid state switch Motor controls Speed sensing Angular Position sensing Linear Position Sensing Current Sensing DESCRIPTION The 65025 Hall effect sensor detects the presence of a magnetic field and provides a switch output. It is packaged in a hermetically sealed three pin ceramic package and can be used in many harsh environments. An internal chopper stabilized amplifier eliminates input offset voltages normally associated with bipolar devices resulting in improved operating point stability. The output transistor will be “latched ON” in the presence of a sufficiently strong South pole magnetic field facing the marked side of the package. The output will be “latched OFF” in the presence of a resetting North pole magnetic field.

Extended temperature performance is obtained with ceramic packaging and assembly processes. High temperature testing is functional switching verification using an applied field of greater than 200 G to latch the output on and an applied field of greater than -200 G to reset output off.
