Limit detection sensor contactless magnetic switch patch magnetic sensitive transistor DH481

It is an omnipolar Hall effect sensor based on mixed-signal technology. It uses advanced chopper stabilization technology to provide accurate and stable magnetic switching points. The circuit design provides a built-in controlled clock mechanism to provide clock sources for Hall devices and analog signal processing circuits. At the same time, this controlled clock mechanism can send out control signals to cause circuits that consume larger currents to periodically enter&; Sleep mode; also through this mechanism, the chip is periodically "awakened" and detects the strength of the external magnetic field passing through the Hall device based on a predetermined magnetic field strength threshold. If the magnetic flux density is higher than the operating point threshold or lower than the release point threshold, the open-drain output transistor is driven and latched into the corresponding state. While during the &;sleep cycle the output transistor is locked in its previous state. This design provides the best support for extended operating life in battery-powered applications. The output transistor of
is locked in the on (B) state when there is a certain strong south or north pole magnetic field on the side facing the package mark, and is locked in the off (BR) state when there is no magnetic field.
