Rad-Hard, 5.0V/3.3V µ-Processor Supervisory Circuits

ISL705ARH, ISL705BRH, ISL705CRH, ISL706ARH, ISL706BRH, ISL706CRH

This family of devices 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.

Specifications for Rad Hard QML devices are controlled by the

Defense Logistics Agency Land and Maritime (DLA). The SMD

numbers listed in the “Ordering Information” table on page 3

must be used when ordering.

Detailed Electrical Specifications for the ISL705ARH,

ISL705BRH, ISL705CRH, ISL706ARH, ISL706BRH and

ISL706CRH are contained in SMD 5962-11213. A “hot-link” is

provided on our website for downloading.

Applications

• Supervisor for µ-Processors, µ-Controllers, FPGAs and DSPs

• Critical Power Supply Monitoring

• Reliable Replacement of Discrete Solutions
