Application principle of Hall switch on refrigerator door: The open and closed state of the door can be sensed by the Hall switch sensor installed near the refrigerator door. When the door is closed, the Hall switch triggers the switch action to notify the refrigerator system to stop the cooling or heating function, saving energy and keeping the temperature of the refrigerator stable.
Recommended model: HS732 high-sensitivity latching speed detection Hall switch
HS732 is a bipolar latching Hall effect sensor based on mixed-signal CMOS technology. The device integrates a voltage regulator, a Hall sensor with a dynamic bias compensation system, a Schmitt trigger and an open-drain output driver, all in one package.
This IC uses advanced chopper stabilization technology, so it can provide accurate and stable magnetic switch points. In addition to the applications listed in the following "Applications", this sensor has many other applications. Its design, parameters and performance are optimized for use in 5V -12V DC brushless motor phase conversion applications.
Because of the wide operating voltage and wide temperature range of the HS732, it is very suitable for use in the automotive, industrial and consumer industries.
This IC has a SOT package for surface mount and a single-row TO-92S flat package that can be directly inserted. Both 3-pin packages are RoHS compliant.
