Description
The ZMID5201, ZMID5202, and ZMID5203 ICs are a family of inductive position sensors, used for absolute rotary and linear motion sensing in automotive, industrial, medical, and consumer applications.
The ZMID520x uses the physical principles of induction in a wire loop and eddy currents to detect the position of an electrically conducting target that is sliding or rotating above a set of coils, consisting of one transmitter coil and two receiver coils.

FEATUREs
◾ Position sensing based on inductive principle
◾ Cost effective, no magnet required
◾ Immune to magnetic stray fields; no shielding required
◾ Suitable for harsh environments and extreme temperatures
◾ Only three wires (ground, supply, output)
◾ Nonvolatile user memory; programming through output pin
◾ Single IC supports on-axis and off-axis rotation, linear motion,
   and arc motion sensing
◾ High resolution, even for small angle ranges
◾ High accuracy: ≤ 0.2% full scale
◾ 9-point user linearization
◾ Rotation sensing up to a full turn of 360º
◾ Overvoltage and reverse-polarity protection:
   -14V to +18V maximum, depending on product
◾ ESD and short-circuit protection
◾ Power or ground loss detection
◾ Facilitates redundant design requirements
◾ Programmable non-linearity correction
◾ Adaptive gain control supporting a wide range of coil designs
   and target displacement
◾ Suitable for implementation in safety-related systems
   compliant to ISO26262 up to ASIL-B

Typical Applications
◾ Rotary position sensors up to 360°; e.g. steering angle
   sensors, potentiometer replacement
◾ Small-angle sensors or arc-motion sensors; e.g. pedal,
   vehicle level, or valve sensors
◾ Linear motion sensors; e.g. linear-actuator position sensors,
   fluid-level sensors
