What are safety-limiting values?
The safety limiting values specify the limits in which the isolation barrier is preserved, even under fault conditions. Exceeding these values can cause damage to the isolation barrier.
In the datasheet, the safety limiting current values refer to the total current through any combination of pins (including the supply and I/O pins) that the device can withstand before damage to the isolation barrier occurs. Similarly, the safety limiting power values given by the datasheet refers to the maximum total power that the device can withstand before damage to the isolation barrier occurs.
