Radiation Hardened Power-Up/Down  
Microprocessor Reset Circuit  
Features  
• Electrically Screened to SMD # 5962-00538  
The Radiation Hardened IS-705RH is  
a monolithic device that monitors the

reset output pulse during power-up and power-down. The  
reset threshold is 4.65V (Typ) and the reset pulse width is set  
at 200ms (Typ). A watchdog circuit is incorporated for easy  
interfacing with microprocessors and controllers. If the  
watchdog input has not been toggled within a preset  
1.6s (Typ) time period, an output signal is generated, which  
can be used as an interupt. The power function input (PFI)  
may be used to monitor other voltage levels. The circuit has a  
1.25V (Typ) threshold and provides a PFO output when low  
voltage is detected. An active-low manual reset input in also  
provided for direct control of the reset function.

Constructed with the Intersil UHF2X-CMOS process, these  
devices have been specifically designed to provide highly  
reliable performance in harsh radiation environments. This
