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 1µA 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 (VIN) is higher than the detect voltage (VDF), the output voltage at VOUT pin equals the input volt-
age at VIN pin.
2. When the input VIN voltage falls lower than VDF, VOUT drops near ground voltage.
3. If the input voltage decreases below the minimum operating voltage (VMIN), the VOUT output voltage will be undefined.
4. During an increase of the input voltage from the VSS voltage, VOUT is undefined at the voltage below VMIN. Exceeding the
VMIN level, the ouput stays at the ground level (VSS) between the minimum operating voltage (VMIN) and the detect release
voltage (VDR).
5. If the input voltage increases more than VDR, the output voltage at VOUT pin equals the input voltage at VIN pin.
6. The difference between VDR and VDF is the hysteresis in the system.
