DIODES Incorporated Supervisors APX803L05-37SA-7

The APX803L05-37SA-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 1µA (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 activates when the monitored voltage falls below the selected threshold. The reset signal remains active until the voltage recovers above the threshold. The APX803L offers several built-in recovery delay time options of 0ms, 55ms, 220ms, and 450ms, accommodating various system requirements. The device is available in multiple package types, including SOT23, SOT323, SC59, and SOT25, and is fully RoHS compliant, ensuring it meets environmental standards. With a high threshold voltage accuracy of ±1.5% and quick reset response time of 20Oºs, the APX803L is a reliable choice for applications in computers, controllers, intelligent instruments, and portable equipment.
