SOT-23 Power Supply reset Monitor With Complementary CMOS Output Impala Linear Corporation Impala Linear Corporation 1(408) 574-3939 www.impalalinear.com June 1999 ILC5062 1.3 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.

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 VIN pin. 2. When the input V IN voltage falls lower than V DF, VOUT drops near ground voltage. 3. If the input voltage decreases below the minimum operat- ing voltage (VMIN), the VOUT 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 (VSS) between the minimum operating voltage (VMIN) and the detect release voltage (V DR). 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 V DR and VDF is the hysteresis in the system. 5431 2 INPUT VOLTAGE (VIN) DETECT RELEASE VOLTAGE (VDR) DETECT FAIL VOLTAGE (VDF) MINIMUM OPERATING VOLTAGE (VMIN) GROUND VOLTAGE (VSS) OUTPUT VOLTAGE (VOUT) GROUND VOLTAGE (VSS) SOT-23 Power Supply reset Monitor With Complementary CMOS Output Impala Linear Corporation 3(408) 574-3939 www.impalalinear.com June 1999 ILC5062 1.3 Functional Description Timing Diagram
