The LN245 is a non-polar Hall effect switch based on mixed-signal CMOS technology. It features advanced chopper-stabilized circuitry for accurate and stable magnetic switch points. The integrated clock mechanism provides timing for the Hall device and analog signal processing, enabling periodic 'sleep' mode for power saving and 'wake-up' for magnetic field detection. The output latching transistor is driven when the magnetic flux density exceeds the 'operate point' threshold or falls below the 'release point' threshold. During sleep cycles, the output transistor remains in its previous state. The output transistor latches ON in the presence of a South or North pole magnetic field and latches OFF in the absence of a magnetic field.
Typical Applications: Mobile phones, laptop computers, portable electronic devices, and more.
