APX803L Micro Power Voltage Detectors

Diodes Incorporated APX803L Micro Power Voltage Detectors are designed for monitoring the power supplies in microprocessors (μP), μC, and digital systems. The APX803L requires a low supply current of only 1.0μA which minimizes the operating current, improving system efficiency on portable, battery-powered devices. High threshold voltage accuracy of +1.5% on the device allows precise VCC reset thresholds. The device circuits perform supervisory functions by sending out a reset signal when the monitored VCC level falls below the chosen threshold voltage level. The reset signal will remain until VCC recovers to a level higher than the threshold voltage, completing the cycle. Another benefit provided is an open-drain output with an active-low output pin that features several delay time options (0ms, 55ms, 220ms, and 450ms) as needed by the system. The packages of 3-pin SOT23, SOT323, SC59, SOT25, and two-pin variants are available on the APX803L Voltage Detectors.
