Overview
Inductive Position Sensor IC IPS2550 Datasheet Description The IPS2550 is a magnet-free, inductive position sensor IC that can be used for high-speed absolute position sensing in automotive, industrial, medical, and consumer applications.
The IPS2550 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 IPS2550 provides two independent output interfaces: ▪ A high-speed analog interface providing position information in the form of demodulated analog sine/cosine raw data ▪ An I2C digital interface for diagnostics and programming The IPS2550 operates at rotation speeds up to 600000 RPM (relating to coil designs using 1 period per turn).
An ultra-low propagation delay of 4µs provides high dynamic control for fast spinning motors.
The IPS2550 has been developed according to ISO26262 for implementation in safety-relevant systems up to ASIL C.
It can also be used in ASIL D system-level requirements according to ASIL Decomposition rules (i.
e.
ISO 26262:2018, Part 9, Clause 5”) or proper risk analysis by the system integrator.
The IPS2550 is available in a 16-pin exposed pad TSSOP package and qualified for automotive use at -40°C to +160°C ambient temperature.
Available Support Renesas provides reference designs that demonstrate IPS2550 rotary position sensing applications.
Typical Applications ▪ Rotor position detection for...
