1 ? fn4703.5 is-705rh radiation hardened power-up/down microprocessor reset circuit 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 microprocesso rs 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/cm 2 . 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. detailed electrical specifications for these devices are contained in smd 5962-00538. a ?hot-link? is provided on our homepage for downloading. http://www.dscc.dla.mil/dow nloads/milspec/smd/00538. pdf features ? electrically screened to smd #5962-00538 ? qml qualified per mil-prf-38535 requirements ? radiation hardness - total dose. . . . . . . . . . . . . . . . . . . . . 100 krad(si) (max) - single event latch-up . . . . . . . . . . . . >90mev/mg/cm 2 ? precision 4.65v voltage monitor ? supply voltage range . . . . . . . . . . . . . . . . . 4.75v to 5.5v ? reset valid at v cc = 1.2v ? low supply current . . . . . . . . . . . . . . . . . . . . 420 a (typ) ? 200ms (typ) reset pulse width ? pb-free plus anneal available (rohs compliant) applications ? flight computers ? controllers ? critical microproce ssor power monitoring ? reliable replacement of discrete solutions pinout is-705rh (8 ld flatpack) top view tm mr v cc gnd pfi 1 2 3 4 8 7 6 5 wdo reset wdi pfo ordering information ordering number internal mkt. number part marking temp. range ( c ) package (pb-free) pkg. dwg. # 5962r0053801qxc is9-705rh-8 q 5962r00 53801qxc -55 to +125 8 ld flatpack, solder sl k8.a 5962r0053801vxc is9-705rh-q q 5962r00 53801vxc -55 to +125 8 ld flatpack, solder sl k8.a 5962r0053801v9a is0-705rh-q -55 to +125 8 ld flatpack, solder sl k8.a is9-705rh/proto is9- 705rh /proto is9- 705rh /proto -55 to +125 8 ld flatpack, solder sl k8.a note: intersil pb-free plus anneal products employ special pb-fre e material sets; molding compounds/die attach materials and 100 % matte tin plate termination finish, which are rohs compliant and compatible wi th both snpb and pb-free soldering operations. intersil pb-free p roducts are msl classified at pb-free peak re flow temperatures that meet or exceed th e pb-free requirements of ipc/jedec j std-020. data sheet august 2, 2007 caution: these devices are sensitive to electrosta tic discharge; follow proper ic handling procedures. 1-888-intersil or 1-888-468-3774 | intersil (and design) is a registered trademark of intersil americas inc. copyright intersil americas inc. 2007. all rights reserved star*power? is a trademark of intersil americas inc.
