Description

The AK8779A 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 AK8779A is for use in the incremental pulse encoders or rotational detection systems.

Key Features

  • Detects vertical and horizontal magnetic fields
    Longitudinal magnetic field and transverse magnetic field can be detected simultaneously.

Applications

  •                                 Consumer, industrial and in-vehicle equipment.
