To confirm, the max output voltage on CS pin (I assume it is called VSENSEH) is 8V according to Table 8 on p11 (https://www.st.com/resource/en/datasheet/vnd5e006asp-e.pdf). But I assume this depends on the sense resistor and ISENSEH of 7mA. What is the max sense resistor can I use to keep the pin below 5V under all conditions incl fault? Is it below ~5V/7mA? Or do I need more margin like 4.5V/7mA given 7mA is typical only? Why does this chip allow 8V for VSENSEH that breaks 5V-IO compatibility. Thanks.
