1 / 35 page  Datasheet IPS2200 Inductive Position Sensor IC Jan.19.21 Page 1 Description The IPS2200 is a magnet-free, inductive position sensor ICs that can be used for high-speed absolute position sensing in industrial, medical, and consumer applications. The IPS2200 uses the physical principle of eddy currents to detect the position of a simple metallic target that is moving above a set of coils, consisting of one transmitter coil and two receiver coils. 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 two receiver coils, which depends on the position of the metallic target above the coils. 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. The IPS2200 provides two independent interfaces: A high-speed analog or digital interface providing position information in the form of demodulated analog sine/cosine raw data or digital incremental outputs An I2C or SPI digital interface for diagnostics and programming The IPS2200 operates at rotation speeds up to 250000 RPM (with coil designs using 1 period per turn). An ultra-low propagation delay down to 10µs or less provides high dynamic control for fast-moving objects. The IPS2200 is available in a TSSOP package and is qualified for industrial use at -40°C to +125°C ambient temperature. Typical Applications Rotor position detection for brushless DC motors; adaptable to any pole pair count Replacement of brushless resolvers Magnet-free rotor speed sensors Features Position sensing based on an inductive principle Cost effective; no magnet required Immune to magnetic stray fields; no shielding required Suitable for harsh environments and extreme temperatures Differential and single-ended sine and cosine outputs Digital incremental outputs: 4 counts per period Nonvolatile user-configurable memory, programmable via I2C or SPI interface Single IC supports on-axis and off-axis rotation, linear motion, and arc motion sensing Adaptable to any full-scale angle range High accuracy: ≤ 0.2% full scale Rotation sensing up to 360º angle range ±18V over-voltage and reverse-polarity protection on output pins Fast diagnostic alarm through interrupt pin Wide operation temperature: -40°C up to +125°C Supply voltage programmable for 3.0V to 3.6V or 4.5V to 5.5V Small 16-TSSOP package (4.4 5.0 mm body) Available Support Renesas provides application modules that demonstrate IPS2200 position sensing, including rotary, arc, and linear applications.
