An omnipolar Hall effect sensor based on mixed signal technology. This sensor uses advanced chopper stabilization technology to provide accurate and stable magnetic switching points.
In terms of circuit design
Provides a built-in controlled clock mechanism to provide clock source for Hall devices and analog signal processing circuits. At the same time, this controlled clock mechanism can send out control signals to make the current consumption larger. The circuit periodically enters the
sleep
mode. The chip is also periodically
awakened
through this mechanism and detects the external magnetic field passing through the Hall device according to the predetermined magnetic field strength threshold. The magnitude of the intensity. 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.
