AK8777B
Hall Effect IC for Pulse Encoders
Overview
The AK8777B 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 output OUTA and OUTB are switched according
to the vertical and horizontal magnetic fields applied to the device. The AK8777B is for use in the incremental pulse
encoders or rotational detection systems.
Features
 4.0 to 24V supply voltage operation
 Sensitivity (Vertical, Horizontal) : ±1.7mT(Typ.)
 Two outputs : OUTA (detects vertical magnetic field), OUTB (detects horizontal magnetic field)
 Small package: SOP-6pin
 Halogen free
