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.
1. A reset output during power-up, power-down, and brownout
conditions.
2. An independent watchdog output that goes low if the
watchdog input has not been toggled within 1.6s.
3. A precision threshold detector for monitoring a power
supply other than V
DD
.
4. An active-low manual-reset input.
Specifications for Rad Hard QML devices are controlled by the
Defense Supply Center in Columbus (DSCC). 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.
