IS-705RH
Features
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.
• Electrically Screened to SMD #5962-00538
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.
