Overview
Description
The IPS2550 is an AEC-Q100 Grade 0 automotive-qualified, inductive position sensor IC capable of providing the absolute rotor position as sine and cosine. This IC uses the physical principle of Eddy currents to detect the position of a simple metallic target moving above a set of coils, consisting of one transmitter and two receivers. The output interface can be configured as single-ended, for higher system cost effectiveness, or differential, to better reject common mode disturbers. The IPS2550 can be used for high-speed motor commutation up to 600krpm electrical in the most challenging automotive functional safety-critical applications.
Stray field immunity, lower weight and smaller size, and a substantial BOM optimization make the IPS2550 the key element of the Resolver 4.0, a disruptive solution.

gui of ips2550
hello. Please tell me about AGC. I wanted to use AGC on the GUI, but when I tried to enable the afe_agc_dis switch, it was forcibly disabled. Is there a register somewhere that allows me to set it? The other registers are adjustable.

IPS2550: can not write configuration through I2C pins. only reading is possible
Hi,We have implemented IPS2550 in our design and we are using dedicated I2C Pins (Pin15 & 16) for communication with our onboard MCU. We have pulled up I2C pins to 5V with a 4K7 resistor on each pin.We can see the output waveform acting correctly, in default configuration ...
