The UT01VS33L is a +3.3V, push-pull RESET, single channel voltage supervisor whose function is to monitor vital supply and signal voltages in microprocessor systems. The single channel voltage supervisor features a fixed voltage threshold of +06V and Vcc and includes a watchdog timer.

The UT01VS33L is ideal for power-on reset controllers for microprocessors, microcontrollers, FPGAs, ASICs and DSPs, and can also be used to sequence multiple power supplies with delays between application of each power supply and the final delay for bringing the part out of reset.

Our family voltage supervisors (UT01VSxxx and UT04VSxxx) may be daisy-chained using the master reset capability, or wired in parallel using the open-drain outputs and ideal to control Frontgrade's Voltage Regulators.
