0V/3.
3V supervisory circuits that reduce the complexity required to monitor supply voltages in microprocessor systems.
These devices significantly improve accuracy and reliability relative to discrete solutions.
Each IC provides four key functions.
• A reset output during power-up, power-down, and brownout conditions.
• An independent watchdog output that goes low if the watchdog input has not been toggled within 1.
6s.
• A precision threshold detector for monitoring a power supply other than VDD.
• An active-low, manual-reset input.
Applications • Supervisor for µ-processors, µ-controllers, FPGAs, and DSPs • Critical power supply monitoring • Reliable replacement of discrete solutions Features • Electrically screened to SMD 5962-11213 • QML qualified per MIL-PRF-38535 requirements • Radiation acceptance testing - ISL705xRH, ISL706xRH - High dose rate .
