9WDV3501BKLF

VOLTAGE MONITOR
The 9WDV3501 contains 5 voltage monitoring (VMON)comparators and a watchdog timer circuit. One of the voltagemonitoring comparators is assigned to monitoring the 3.3Vsupply rail, while the other 4 are available externally to allow theuser to monitor an additional 4 supply rails. The external voltagemonitor inputs have a reset threshold of approximately 1.0V.Various power supplies can easily be monitored with theseinputs by use of a simple resistor ladder to divide the supply raildown to 1.0V.
