The UT01VS50L’s function is to monitor vital supply and signal voltages in microprocessor systems. It provides for safe reset during power up, power down and brownout conditions by using an internal precision voltage reference.  The UT01VS50L monitors activity at an independent watchdog input by employing an internal timer and a watchdog output that goes low if the input is not toggled within 1.6s. It provides for precision voltage threshold detection on an independent voltage input which could be used for battery or supply-low monitoring of a supply voltage other than VDD.  The UT01VS50L includes an active low manual reset with an internal pull-up.
