Overview

The AK8778B is a Hall effect latch which detects both “vertical magnetic field” and “horizontal magnetic field” (perpendicular and parallel to the marking side of the package) at the same time. The pulse output F and direction output D are switched according to the vertical and horizontal magnetic fields applied to the device. The direction

is calculated internally and output D is switched at a rising or falling edge of output F. The AK8778B is for use in

the incremental pulse encoders or rotational detection systems.
