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.
  • Detection output signal of alternating magnetic field change
    The alternating magnetic field detection signal of the vertical magnetic field is output from the OUTA terminal, and the alternating magnetic field detection signal of the horizontal magnetic field is output from the OUTB terminal.

Applications

  •                                 Consumer, industrial and in-vehicle equipment.
