Renesas IPS2200STKIT

Overview

IPS2200STKIT from Renesas is an evaluation kit for the IPS2200 magnet-free inductive position sensor IC, designed to demonstrate rotary, linear, and arc motion sensing using printed PCB coils and metallic targets. It supports 3.3 V or 5 V supply, delivers ≤0.2% full-scale accuracy, enables up to 250,000 RPM rotor sensing, and features dual digital interfaces (I²C/SPI) plus analog/digital outputs (SIN/COS/AB quadrature).

For engineers reviewing the IPS2200STKIT datasheet, IPS2200STKIT pinout, IPS2200STKIT application, or IPS2200STKIT equivalent, this kit provides validated coil layouts, real-time diagnostics, programmable LC oscillator tuning, and configurable output modes - essential for rapid prototyping of brushless motor rotor position feedback, resolver replacement, and harsh-environment industrial motion sensing.

Technical Context

The IPS2200STKIT implements the IPS2200 IC's eddy-current-based sensing architecture, where a single transmitter coil (TX1/TX2) excites two differential receiver coil pairs (RX1/RX2 for sine; RX3/RX4 for cosine) on a custom PCB. Position is derived from amplitude-modulated demodulation of induced voltages, independent of target material (aluminum, steel, copper).

It supports three primary output configurations: differential analog sine/cosine (OUT1–OUT4), single-ended analog with internal bias references, and digital AB incremental quadrature (4 counts per period). Propagation delay is ≤10 µs, and diagnostics include LC oscillator frequency monitoring, over/under-voltage alarms, and interrupt-driven fault reporting via CSN_IRQN.

FAQ

What is the primary purpose of the IPS2200STKIT?

The IPS2200STKIT is a hardware evaluation kit for the IPS2200 inductive position sensor IC. It includes a populated PCB with optimized transmitter/receiver coil patterns, interface headers, and jumpers to configure supply voltage (3.3 V or 5 V), output mode (analog or digital), and communication interface (I²C or SPI). Its purpose is to accelerate development of magnet-free position sensing systems - not to serve as a production sensor module. The IPS2200STKIT validates coil design, signal integrity, and firmware integration before custom board spin.

Does the IPS2200STKIT include the IPS2200 IC?

Yes, the IPS2200STKIT includes one fully assembled and tested IPS2200 IC in a 16-TSSOP package mounted on the evaluation board. The IC is pre-programmed with factory-default settings and supports in-system configuration via I²C or SPI. All critical pins - including TX1/TX2, RX1–RX4, OUT1–OUT4, SIO_SDA, SCK_SCL, and CSN_IRQN - are brought out to 0.1″ headers or test points for oscilloscope probing and host MCU connection.

Can the IPS2200STKIT be used for linear position sensing?

Yes, the IPS2200STKIT supports linear motion sensing using its included linear coil layout (per Figure 6 of the IPS2200 datasheet). The board provides dedicated copper traces for linear target translation above the transmitter and receiver coils. When paired with a conductive slider (e.g., aluminum or copper), the IPS2200 IC outputs proportional sine/cosine or AB quadrature signals corresponding to absolute linear displacement - calibrated via NVM programming to match mechanical stroke length.

What coil configurations are supported by the IPS2200STKIT?

The IPS2200STKIT supports multiple coil topologies: a 360° rotary pattern (1-period-per-turn), 2×180°, 3×120°, and 4×90° multi-period rotary layouts, plus a linear motion pattern. Each uses etched copper traces on the same PCB, with jumpers to select active coil set. These configurations allow users to validate mechanical accuracy (e.g., ±0.24° for 3×120°) and optimize resolution/speed trade-offs without redesigning hardware - directly leveraging the IPS2200 IC's programmable scaling and period detection.

How does the IPS2200STKIT handle diagnostics and fault reporting?

The IPS2200STKIT enables comprehensive diagnostics via the IPS2200 IC's built-in features: LC oscillator frequency monitoring (programmable 7 kHz–10 MHz range), VDD/VDDA over/under-voltage detection, register memory CRC checks, and coil open/short detection. Faults trigger a push-pull interrupt on the CSN_IRQN pin, which is routed to a header and LED indicator. Diagnostic status is also readable via I²C/SPI registers (e.g., STATUS_DIAG, ALARM_CFG), allowing host firmware to log errors or initiate safe shutdown - critical for functional safety validation.
