Radiation Hardened, 5.0V/3.3V µ-Processor Supervisory Circuits
The devices in this family (ISL705AEH, ISL705BEH, ISL705CEH, ISL705ARH, ISL705BRH, ISL705CRH, ISL706AEH, ISL706BEH, ISL706CEH, ISL706ARH, ISL706BRH, ISL706CRH, ISL735AEH, ISL735BEH, ISL735CEH, ISL736AEH, ISL736BEH, ISL736CEH) are radiation hardened 5.0V/3.3V supervisory circuits that reduce the complexity required to monitor supply voltages in microprocessor systems. These devices significantly improve accuracy and reliability relative to discrete solutions. Each IC provides four key functions.
A reset output during power-up, power-down, and brownout conditions.
An independent watchdog output that goes low if the watchdog input has not been toggled within 1.6s.
A precision threshold detector for monitoring a power supply other than VDD.
An active-low, manual-reset input.
Applications
Supervisor for µ-processors, µ-controllers, FPGAs, and DSPs
Critical power supply monitoring
Reliable replacement of discrete solutions
