MT613X series wafers are a reluctance switch sensor IC, which can detect the magnetic field parallel to the IC package. The chip is based on the single-chip process and integrates AMR sensors and ASICs on a single chip for a variety of applications in the industrial and automotive markets.
MT613X series wafer based on the Y axis parallel induction of MT611X series wafer has been expanded and upgraded, so that the induction can be carried out in the plane where the X axis and Y axis are located (also known as 2D induction), realizing the function of 360° parallel induction, and has a stable magnetic sensitivity at all angles, BOP: ±18 / BRP: ±13, two different operating frequencies (20Hz and 1KHz) are available according to customer requirements. MT613X series has a wide induction Angle and strong magnetic sensitivity, has been widely used in the wisdom of three tables, to achieve anti-magnetic theft attack and flow count function; It can be used in industrial and automobile level gauges to realize the function of liquid level detection.
The IC internal includes a wheatstone bridge with magnetic film, one for work under 1.65 V to 5.0 V power supply voltage of the current regulator, one for the sleep/wake logic of low power requirements, small signal amplifier and belt dynamic offset to eliminate the Schmitt trigger comparator, and a push-pull output and the open circuit output two different options for the output of the drive.
