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.
• 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

NOTE:
1. Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed must be
used when ordering.
2. These Intersil Pb-free Hermetic packaged products employ 100% Au plate - e4 termination finish, which is RoHS compliant and compatible with both
SnPb and Pb-free soldering operations.
3. The /PROTO and /SAMPLE are not rated or certified for Total Ionizing Dose (TID) or Single Event Effect (SEE) immunity. These parts are intended for
engineering evaluation purposes only. The /PROTO parts meet the electrical limits and conditions across the temperature range specified in the DLA
SMD and are in the same form and fit as the qualified device. The /SAMPLE die is capable of meeting the electrical limits and conditions specified
in the DLA SMD at +25°C only. The /SAMPLE is a die and does not receive 100% screening across the temperature range to the DLA SMD electrical
limits. These part types do not come with a certificate of conformance because there is no radiation assurance testing and they are not DLA qualified
devices.
4. Evaluation board uses the /PROTO parts. The /PROTO parts are not rated or certified for Total Ionizing Dose (TID) or Single Event Effect (SEE) immunity.

DESCRIPTION
Manual Reset. MR is an active-low, debounced, TTL/CMOS compatible input that can
be used to trigger a reset pulse.
Power Supply. VDD is a supply voltage input that provides power to all internal circuitry.
This input is also monitored and used to trigger a reset pulse. Reset is guaranteed
operable after VDD rises above 1.2V.
Ground. GND is a supply voltage return for all internal circuitry. This return establishes
the reference level for voltage detection and should be connected to signal ground.
Power Fail Input. PFI is an input to a threshold detector, which can be used to monitor
another supply voltage level. The threshold of the detector (VPFI) is 1.25V in the
ISL705AxH/BxH/CxH and 0.6V in the ISL706AxH/BxH/CxH.
Power Fail Output. PFO is an active-low, push-pull output of a threshold detector that
indicates the voltage at the PFI pin is less than VPFI.
