TPS7B7701-Q1: 诊断输出短路到电源(short to battery)时 ,ERR是高,没有拉低,SENSE1 ADC通道值是0

Part Number: TPS7B7701-Q1

Hi TI expert,

    

      FM天线诊断电路上用的TItps7b7701芯片,现在遇到一个问题,天线输出short-to-battery情况下,ERR pin没有被拉低,读SENSE1 ADC通道值是0,看起来和Datasheet page13上不一致,

 

      天线开路open load时候,ADC读值也是0,和short-to-battery就无法区分了,请看下这个问题,谢谢!
