Rad-Hard, 5.0V/3.3V Microprocessor Supervisory Circuits
Jump to Page Section:
Overview
Description
The devices in this family 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, and an active-low, manual-reset input.

- Precision threshold detector
- 1.25V threshold in the ISL7x5AxH/BxH/CxH
- Debounced TTL/CMOS compatible manual-reset input
- Reset output valid at VDD = 1.2V
