Radiation Hardened, 5.0V/3.3V µ-Processor Supervisory Circuits
The devices in this family are radiation hardened 5.0V/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 V
DD
.
• An active-low, manual-reset input.
