Product overview

The UT01VS33L monitors supply and signal voltages in microprocessor-based systems. An internal precision reference supports reset control during power-up, power-down and brownout conditions. An independent watchdog monitors activity at the watchdog input and asserts an output when the input is not toggled within the specified interval. A separate voltage-monitor input can supervise a battery or another supply rail. The push-pull reset output and manual-reset input provide a defined interface to the host system. These functions combine supply supervision and activity monitoring for processors, controllers, DSPs and FPGAs.
