Radiation Hardened, 5.0V/3.3V -Processor Supervisory Circuits
Apr 23, 2020
The devices in this family are radiation hardened 5.0V/3.3V
Features
supervisory circuits that reduce the complexity required to
Electrically screened to SMD 5962-11213
monitor supply voltages in microprocessor systems. These
devices significantly improve accuracy and reliability relative to
QML qualified per MIL-PRF-38535 requirements
discrete solutions. Each IC provides four key functions.
