Tool/software:

Hello,

we are verifying the function of TI ideal diode LM74202, but we found the OVP cut off function is not working.

the voltage in OVP is 1.3V > 1.19V and the output voltage is already activated !, please find below our measurements and schematic.

    Hello Salah,

    Is this occurring in one IC or multiple?

    Can you check with replacing another IC and check if same issue is occurring?

    You are checking the OVP voltage exactly on the pin or on the resistor divider?

    Asking this to check if there is any soldering issue between IC pin and PCB.

    Thanks
