DIODES Incorporated Supervisors APX803L-18W5-7

The APX803L-18W5-7 is a micro-power voltage detector designed for supervisory circuits in microprocessor and digital systems. It features a wide detection voltage range from 1.2V to 5.0V with 0.1V step options, allowing for precise voltage monitoring. The device operates with a low supply current of 1¬µA (typical), making it suitable for battery-powered applications and devices where power efficiency is critical. This voltage detector provides an open-drain output with an active-low reset signal, which is triggered when the monitored voltage falls below the selected threshold. The reset signal remains active until the voltage recovers above the threshold level. The APX803L offers several built-in recovery delay time options of 0ms, 55ms, 220ms, and 450ms, accommodating various system requirements. The product is available in multiple package types, including SOT23, SOT323, SC59, and SOT25, and is compliant with RoHS standards, ensuring it is free from harmful substances. With a high threshold voltage accuracy of ¬±1.5% and quick reset response time of 20Oºs, the APX803L-18W5-7 is a reliable choice for applications in computers, controllers, intelligent instruments, and other critical power monitoring systems.
