NOTE:
Principles of Operation
The ISL88705, ISL88706, ISL88707, ISL88708, ISL88716,
ISL88813 devices provide those functions needed for
monitoring critical voltages such as power-supply and battery
functions in microprocessor systems. Features of these
supervisors include Power-On Reset control, Supply Voltage
Supervision, Power-Fail Detection and Manual Reset
Assertion. The integration of all these features along with high
reset threshold accuracy and low power consumption make
these devices ideal for portable or battery-powered equipment.

CONDITIONS
Power-On Reset (POR)
Applying power to the device activates a POR circuit which
asserts reset (i.e. RST goes high while RST goes low). These
signals provide several benefits:
• It prevents the system microprocessor from starting to
• It prevents the processor from operating prior to stabilization
• It ensures that the monitored device is held out of operation
• It allows time for an FPGA to download its configuration prior
The reset signals remain active until V
minimum voltage sense level for time period t
ensures that the supply voltage has stabilized to sufficient
operating levels.
