Part Number: PGA411-Q1


Hi team

I am looking for a vehicle Resolver related device.

Found PGA411-Q1.

Is there only one of these?

Let me know about other recommended devices

Thanks,

TM

    TM,

    PGA411-Q1 is the only integrated resolver to digital converter available from TI. A few of the important features are:

    - 12 bit resolution with about +-3LSB of angle accuracy, up to 72,000 RPM is supported in this mode
    - 10 bit resolution up to 200,000 RPM
    - up to 145mA peak output current for the excitation signal
    - 10kHz to 20kHz excitation signal
    - SPI, parallel (14 pins in 12 bit mode), or emulated encoder outputs

    (the PGA411-Q1 has many more features, including diagnostic capabilities; however, the ones I have listed are the first things you should check for in your system)

    If these parameters match your application, then this should be a good fit for you. You need to check that the PGA411 will work with your resolver sensor, and that the angle/velocity resolution and accuracy is good enough for your system.

    Thanks,
