The UT01VS50L is a +5.0V, 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 +1.25V and Vcc and includes a watchdog timer. The UT01VS50L 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.
Features:
- 4.75V to 5.5V Operating voltage range
- Power supply (VDD) monitor set by the internal voltage reference at 4.65V
