AK8779A
Hall Effect IC for Pulse Encoders
1. General Description
The AK8779A is a Hall effect latch which detects both “vertical magnetic field” and “horizontal magnetic
field” (perpendicular and parallel to the marked side of the package) at the same time. The pulse output
F and the 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 on a rising or falling edge of
output F. The AK8779A is for use in the incremental pulse encoders or rotational detection systems.
