IS-705RH NORTECROEMCIOMSMEL7NM5DE0EN5DADEERHDE,PFISLOALR7C0NE5EMAWERNHDTEPSAIGRNTS Radiation Hardened Power-Up/Down Microprocessor Reset Circuit DATASHEET FN4703 Rev 6.00 March 23, 2010 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.
