Radiation Hardened Power-Up/Down

Microprocessor Reset Circuit

Features

• Electrically Screened to SMD # 5962-00538

The Radiation Hardened IS-705RH is

a monolithic device that monitors the

• QML Qualified per MIL-PRF-38535 Requirements

• Radiation Hardness

power supply voltage used by

satellite control units and provides a

- Total Dose. . . . . . . . . . . . . . . . . . . . . 100 krad(Si) (Max)

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.

- Single Event Latch-up . . . . . . . . . . . . >90MeV/mg/cm

• Precision 4.65V Voltage Monitor

• Wide Operating Supply Range . . . . . . . . . . . 1.2V to 5.5V

• Low Supply Current . . . . . . . . . . . . . . . . . . . . 420µA (Typ)

• 200ms (Typ) RESET Pulse Width

Applications

• Flight Computers

• Controllers

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

• Critical Microprocessor Power Monitoring

• Reliable Replacement of Discrete Solutions
