Inductive Position Sensor IC

Features

Datasheet

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.

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)

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.

Nonvolatile user memory; programming through output pin

Single IC supports on-axis and off-axis rotation, linear motion,

and arc motion sensing

The three coils are typically printed as copper traces on a printed

circuit board (PCB). They are arranged such that the transmitter

coil induces a secondary voltage in the receiver coils that

depends on the position of the metallic target above the coils.

High resolution, even for small angle ranges

High accuracy: ≤ 0.2% full scale

9-point user linearization

A signal representative of the target’s position over the coils is

obtained by demodulating and processing the secondary voltages

from the receiver coils. The target can be any kind of metal, such

as aluminum, steel or a PCB with a printed copper layer.

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

The ZMID5201/-02-/03 ICs are fully qualified to the automotive

standard AEC-Q 100, grade 0 from -40°C up to 150°C ambient

temperature.

Power or ground loss detection

Facilitates redundant design requirements

Programmable non-linearity correction

Three versions with different output interfaces are available:

Adaptive gain control supporting a wide range of coil designs

and target displacement

ZMID5201: Analog output

ZMID5202: PWM digital output

ZMID5203: SENT digital output

Suitable for implementation in safety-related systems

compliant to ISO26262 up to ASIL-B
