If the supply voltage exceeds the max operating
supply voltage value, an internal comparator dis-

nal powerMOS.
In bothcasesthe thresholdsare providedwith suit-
able hysteresisvalues.

to withstand- for a limited time - highovervoltages.
It consists of an active clamping diodewhich limits
the circuit supplyvoltage toV

andan external
current limiting resistor R1. The maximum pulse
