General Description

The XL561 is an omnipolar Hall switch sensor

that optimized for wide voltage, low quiescent

current and wide temperature range. XL561

supports a power supply voltage of up to

50V and provide a load capacity of up to

50mA. Widely used in automotive electronics,

industrial control and other applications.

Adopting a collector open circuit output

architecture, it has strong resistance to

electromagnetic interference.

The XL561 integrates a reference voltage

source, temperature compensation, Hall

array, differential comparator, hysteresis

latch, and power output stage, providing high

magnetic field consistency, and strong

immunity to electromagnetic interference

over the full voltage range and full

temperature range.
