ILC5062
SOT-23 Power Supply reset Monitor
With Complementary CMOS Output
General Description
All-CMOS voltage monitoring circuit in a 3-lead SOT-23
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 micro-
processor applications. Even though its output can sink
over 2mA, the device draws only 1µA in normal operation.
Additionally, a built-in hysteresis of 5% of detect voltage
simplifies system design.

SOT-23 Power Supply reset Monitor With Complementary CMOS Output
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 voltage 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 operat-
ing 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.
