Tool/software:
A voltage monitoring circuit is designed to monitor 300V output from the PSFB converter. We set 1.7V as threshold at isolation amplifier (AMC1311BDWVR) to monitor the maximum voltage of 300V. We got a maximum output voltage of 2.33V at OUTP and 0.542V at OUTN pins of AMC1311BDWVR. We are directly connecting the OUTP and OUTN of AMC1311 to the primary microcontroller (UCD3138ARGCR) differential pins (EAP0 and EAN0)
But the maximum voltage supported by the EAP0 is 1.999V as per UCD3138ARGCR datasheet. Please suggest any approach to reduce the voltage at OUTP such that it is supported by EAP01 pin of UCD3138ARGCR.
