Description
All-CMOS voltage monitoring circuit in either a 3-lead
SOT-23 or SC70 package offers the best performance in
power consumption and accuracy.
The ILC5062 is available in a series of 1% (A-grade) or 2%
(standard grade) accurate trip voltages to fit most micropro-
cessor applications. Even though its output can sink over
2mA, the device draws only 1A in normal operation.
Additionally, a built-in hysteresis of 5% of detect voltage
simplifies system design.

Functional Description
The following designators 1~6 refer to the timing diagram below.
1. While the input voltage (V
IN
) is higher than the detect voltage (V
DF
), the output voltage at V
OUT
pin equals the input volt-
age at V
IN
pin.
2. When the input V
IN
voltage falls lower than V
DF
, V
OUT
drops near ground voltage.
3. If the input voltage decreases below the minimum operating voltage (V
MIN
), the V
OUT
output voltage will be undefined.
4. During an increase of the input voltage from the V
SS
voltage, V
OUT
is undefined at the voltage below V
MIN
. Exceeding the
V
MIN
level, the ouput stays at the ground level (V
SS
) between the minimum operating voltage (V
MIN
) and the detect release
voltage (V
DR
).
5. If the input voltage increases more than V
DR
, the output voltage at V
OUT
pin equals the input voltage at V
IN
pin.
6. The difference between V
DR
and V
DF
is the hysteresis in the system.
