3.3 Early warning
This circuit compares the EW
i
input signal with the internal voltage reference (typically
2.5 V). The use of an external voltage divider makes the comparator very flexible in the
application. This function can be used to supervise the supply input voltage either before or
after the protection diode and to give additional information to the microprocessor such as
low voltage warnings.
