AK8775
Hall IC for Pulse Encoder
Overview
AK8775 is a Hall effect latch which detects both “vertical” and “horizontal”(perpendicular and parallel to the
marking side of the package) magnetic field at the same time. The result of Hall effect latch operation in vertical and
horizontal magnetic field is read out to OUTA pin and OUTB pin. AK8775 is for use in portable devices which uses
rotational detection system or incremental pulse encoder such as jog dial utilized for input devices.
Features
o 1.6 to 5.5V operation
o Bop, Brp (Vertical, Horizontal) ±1.5mT(Typ.), Highly sensitive
o Low power operation : Average 90μA(Typ.) @V_DD=3V
o Two outputs : OUTA (detects vertical magnetic field), OUTB (detects horizontal magnetic field)
o Small package: SOP-4pin, Halogen free
