Datasheet IPS2200 Inductive Position Sensor IC Description Features The IPS2200 is a magnet-free, inductive position Position sensing based on an inductive principle sensor ICs that can be used for high-speed absolute Cost effective no magnet required position sensing in industrial, medical, and consumer Immune to magnetic stray fields no shielding applications. The IPS2200 uses the physical principle required of eddy currents to detect the position of a simple Suitable for harsh environments and extreme metallic target that is moving above a set of coils, temperatures consisting of one transmitter coil and two receiver coils. Differential and single-ended sine and cosine outputs The three coils are typically printed as copper traces on Digital incremental outputs: 4 counts per period a printed circuit board (PCB). They are arranged such that the transmitter coil induces a secondary voltage in Nonvolatile user-configurable memory, the two receiver coils, which depends on the position of programmable via I2C or SPI interface the metallic target above the coils. Single IC supports on-axis and off-axis rotation, linear motion, and arc motion sensing A signal representative of the targets position over the coils is obtained by demodulating and processing the Adaptable to any full-scale angle range secondary voltages from the receiver coils. The target High accuracy: 0.2% full scale can be any kind of metal, such as aluminum, steel, or a Rotation sensing up to 360 angle range PCB with a printed copper layer. 18V over-voltage and reverse-polarity protection on The IPS2200 provides two independent interfaces: output pins A high-speed analog or digital interface providing Fast diagnostic alarm through interrupt pin position information in the form of demodulated analog sine/cosine raw data or digital incremental Wide operation temperature: -40C up to +125C outputs Supply voltage programmable for 3.0V to 3.6V or An I2C or SPI digital interface for diagnostics and 4.5V to 5.5V programming Small 16-TSSOP package (4.4 5.0 mm body) The IPS2200 operates at rotation speeds up to 250000 Available Support RPM (with coil designs using 1 period per turn). An ultra-low propagation delay down to 10s or less Renesas provides application modules that provides high dynamic control for fast-moving objects. demonstrate IPS2200 position sensing, including rotary, arc, and linear applications. The IPS2200 is available in a TSSOP package and is qualified for industrial use at -40C to +125C ambient Application Circuit Example temperature.
