The device provides embedded protective functions. Integrated protection functions are designed to prevent the
destruction of the IC from fault conditions described in the data sheet. Fault conditions are considered as “outside”
normal operating range. Protection functions are designed for neither continuous nor repetitive operation.
6.1
Below V
the device is OFF (turns OFF). As soon as the supply voltage is above the under voltage mechanism, then the
device can be switched ON and the protection functions are operational.
6.2
There is a clamp mechanism for over voltage protection. To guarantee this mechanism operates properly in the
application, the current in the zener diode
application to withstand overvoltage issues. In case of supply greater than
ON and the voltage across logic section is clamped. As a result, the internal ground potential rises to
Due to the ESD zener diodes, the potential at pin IN rises almost to that potential, depending on the impedance
of the connected circuitry. Integrated resistors are provided at the IN pin to protect the input circuitry from
excessive current flow during this condition.

compared to normal mode. This specially impacts the short circuit robustness, as well as the maximum energy
