MIC5021 High -Side Fet driver without Current Sensing
I am using a MIC5021 and have disabled Current Sensing (datasheet chapter 6.8) by connecting the sense inputs to power supply. I have also disabled retries by connecting Ct to ground (chapter 5.4). I notice the driver sometimes doesn't respond to the input, a power down is necessary to get the driver functioning again. I expect the driver comes in an overcurrent fault.
But how can it detect an overcurrent if the sense inputs are connected together to supply? Does someone recognize this issue?
