Fan Controller Operation AMC6821Q1

Fan Controller Operation AMC6821Q1

    Hello,

     

    I had a couple questions about the AMC6821. I was wondering if the IC can still provide PWM to the fan by referencing only the internal temperature sensor, or does the IC have to have the external diode temperature sensor to make a reference to. Also, I wanted to double check that the IC can still run properly even after I2C communication is terminated. Any help would be greatly appreciated.

     

    Thanks!

    -Matt

    Hello Matthew,

     

    I’ve been out of the office (last week) but back now and I wanted to touch base with you on this. Our Factory Apps. folks for this device are currently testing the EVM to see if the device supports the application you described. They also provided the attached “write-up”. Do you have additional concerns or questions?

    Best Regards,

    Jeff Pfarr
