e2e,
For the analog input voltage, the TS5A3159-Q1 spec mentions max value is V+ + 0.5V, but in note(3), it mentions that the output voltage rating may also be exceeded if the input and output clamp-current rating are observed.
In my application, there is a scenario that the input will be short to battery(12V), so I want to use a diode to clamp the input voltage to V+, the diode will have about 0.6V forward voltage, then VNO will be 5+0.6V, higher than 5.5Vspec, but if I add a resistor to clamp the current within 50mA, is it safe for the device to work? Or should I clamp the current to other spec? Thanks.
