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 Features Electrically screened to SMD 5962-11213 QML qualified per MIL-PRF-38535 requirements Radiation acceptance testing - ISL705xRH, ISL706xRH - High dose rate . . . . . . . . . . . . . . . . . . . . . . . . . . 100krad(Si) Radiation acceptance testing - ISL705xEH, ISL706xEH - High dose rate . . . . . . . . . . . . . . . . . . . . . . . . . . 100krad(Si) - Low dose rate . . . . . . . . . . . . . . . ...
