* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

FUNCTIONAL DESCRIPTION
The IL75XX series is the set of voltage detectors equipped with a high stability voltage reference which is connected
to the negative input of a comparator denoted as VREF in block diagram.
When the voltage drop to the positive input of the comparator (VB) is high than VREF, VOUT goes high. If VCC is
decreased so that VB falls to a value less than VREF, the comparator output inverts from high to low, VOUT goes low. The
device has hysteresis to prevent the circuit from oscillation when VB  VREF. If VCC falls below the minimum operating
voltage, the output becomes undefined. The detectable voltage is defined as:
VDET    

The release voltage is defined as:

The hysteresis width is:
