The Hall element DH481 is a Hall IC designed and manufactured based on CMOS technology. The element integrates a Hall effect plate, voltage regulator, sleep-wake control circuit, signal amplification and filtering circuit, offset compensation circuit, Schmitt trigger, and complementary push-pull output. This IC employs advanced chopper stabilization technology, enabling it to provide accurate and stable magnetic switching points. The internal controlled clock mechanism supplies a clock source for the Hall device and analog signal processing circuit. The Hall sensor DH481 operates through periodic sleep and wake cycles to achieve reduced power consumption. During the wake phase, it detects the ambient magnetic field strength, while in the sleep state, it maintains the last output status.
