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
In case of loss of the module ground, where the load remains connected to ground, the device protects itself by
automatically turning OFF (when it was previously ON) or remains OFF, regardless of the voltage applied on IN
pins. In that case, a maximum

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.
6.3
There is a clamp mechanism for over voltage protection. To guarantee this mechanism operates properly in the
application, the current in the zener diode ZD
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 pins IN and ST 0/1/2/3 rises almost to that potential, depending on
the impedance of the connected circuitry. Integrated resistors are provided at the IN pins to protect the input
circuitry from excessive current flow during this condition but an external resistor must be provided at the ST0/1/2/3
pins.
