Product overview
The UT04VS33P is a radiation-hardened by design voltage supervisor, which simultaneously monitors up to four supply levels utilized in a system, providing status output for each signal, VOUTx, as well as, a system reset signal if any of the monitored signals moves out of range. The UT04VS33P 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.
