Low-Power Omnipolar Hall Switch Sensor
This is a low-power omnipolar Hall switch sensor designed for space-constrained and battery-sensitive systems. It offers multiple magnetic threshold options, switch frequencies, and comes in an SOT-553 package for a wide range of non-contact detection applications. The chip operates over a wide voltage range of 1.6V to 5.5V, features omnipolar magnetic detection with CMOS push-pull output, and incorporates a temperature compensation circuit for stable performance.
