Description
The Radiation Hardened IS-705RH is a monolithic device that monitors the power supply voltage used by satellite control units and provides a 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 process has been tested for single event latch-up and has demonstrated an immunity to 90MeV/mg/cm2.
Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed here must be used when ordering.
