| Radiation Hardened Power-Up/Down Microprocessor Reset Circuit IS-705RH 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 interrupt. 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 is also provided for direct control of the reset function.
