Hello

              If customer would like to disable AGL function of TPA3144D2, change 56K to 0 ohm resistor to let LIMTHER and LIMRATE pins connect to GVDD. Has any question for this schematics modify to disable AGL? Thank you.

    Hi Patrick,

    Setting LIMRATE pin to GND disables AGL function and enable PLIMIT function. Please find more info in the Table 2 in the TPA3144D2 datasheet: 

    To disbale PLIMIT fucntion, set GVDD voltlage to LIMTHRES. Pleae find more explanation in the section 9.3.6 in the datasheet.

    Best regards,

    Shawn Zheng
