www.fairchildsemi.com ILC5062 SOT-23 Power Supply reset Monitor with 1% precision Features • • • • • • • All-CMOS design in SOT-23 or SC70 package A grade ±1% precision in Reset Detection Standard grade : ±2% precision in Reset Detection Only 1µA of Iq Over 2mA of sink current capability Built-in hysteresis of 5% of detection voltage Voltage options of 2.6, 2.7, 2.8, 2.9, 3.1, 4.4, and 4.6V fit most supervisory applications • Active low push-pull output 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 microprocessor 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.

While the input voltage (VIN) is higher than the detect voltage (VDF), the output voltage at VOUT pin equals the input voltage 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.
