AK8778
Hall Effect IC for Pulse Encoders
Overview
The AK8778 is a Hall effect latch which detects both âvertical magnetic fieldâ and âhorizontal magnetic fieldâ
(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 AK8778 is for use in the
incremental pulse encoders or rotational detection systems.
