CH463A/AN

DESCRIPTION

The CH463A and CH463AN are small, versatile digital Hall effect devices that are operated by the 

magnetic field from a permanent magnet or an electromagnet, designed to respond to alternating North 

and South poles.

These bipolar latching sensor ICs have enhanced sensitivity, which often allows for the use of less 

expensive magnets.

These sensor ICs are available in two package styles, the CH463AS/CH463ANS in the subminiature 

SOT-23-3L surface mount package and the CH463AT/ CH463ANT in the leaded, flat TO-92S package.

The CH463AS/CH463ANS’s small size requires less PC board space, allowing it to be used in smaller 

assemblies. Its 3.5V capability allows for use in low voltage applications, promoting energy efficiency.

The CH463AS/CH463ANS is available on tape and reel; the CH463AT/ CH463ANT is available in a bulk 

package (1000 units per bag).
