ILC5061 1.7
All-CMOS Monitor circuits in a 3-lead SOT-23 package offer the
best performance in power consumption and accuracy.
The ILC5061 comes in a series of ±1% accurate trip voltages to
fit most microprocessor applications. Even though its output
can sink 2mA, the device draws only 1µA in normal operation.
Additionally, a built-in hysteresis of 5% of detect voltage
simplifies system design.
• All-CMOS design in SOT-23 and SOT-89 package
• ±1% precision in Reset Detection
• Only 1µA of Iq
• 2mA of sink current capability
• Built-in hysteresis of 5% of detection voltage
• Voltage options of 2.6, 2.9, 3.1, 4.4, and 4.6V fit most
supervisory applications
• Microprocessor reset circuits
• Memory battery back-up circuitry
• Power-on reset circuits
• Portable and battery powered electronics

The following designators 1~6 refer to the timing diagram below.
1. While the input voltage (V
IN
) is higher than the detect volt-
age (VDF), the V
OUT
output pin is at high impedance state.
2. When the input VIN voltage falls lower than VDF, V
OUT
drops near to ground voltage
3. If the input voltage further decreases below the minimum operating voltage (V
MIN
), the V
OUT
output becomes
unstable. In this condition, if the V
OUT
pin is pulled up,
V
OUT
indicates the VINvoltage.
4. During an increase of the input voltage from the V
SS
voltage, V
OUT
is not stable in the voltage below the V
MIN
.
Exceeding that level, the output stays at the ground level
(VSS) between the minimum operating voltage (V
MIN
) and
the detect release voltage (VDR).
5. If the input voltage increases more than VDR, then the
V
OUT
output pin is at high impedance state.
6. The difference between VDR and VDF is the hysteresis
in the system.
