Hello,
I am designing circuit that is used ISOW7844DWE.
Voltage clamp circuit is connected ISOW7844DWE input (INx) to clamp to voltage of 5V from 30V external input voltage.
This voltage clamp circuit consists 100kohm current limit resistor and two clamp diodes (one of the diode is connected to VISO and another one is connected to GND2).
Output voltage of this voltage clamp circuit is approximate VISO + 0.6V.
Absolute maximum rating of ISOW7844DWE input voltage is "VISO + 0.5V (3)" on the datasheet.
Contents of the note(3) is "This value depends on whether the pin is located on the VCC or VISO side. The maximum voltage at the I/O pins should not exceed 6V"
I would like to check if there is a problem with the ISOW7844DWE for input voltage of VISO + 0.6V.
Regards,
MESH
