ADPL62086 Supervisory Circuits

Introduction

The ADPL62086 Supervisory Circuits from Analog Devices / Maxim Integrated is a versatile component designed to monitor voltage levels in various applications. With its ability to operate across a wide temperature range and its factory-set reset thresholds, this supervisory circuit is an essential part for ensuring reliable operation in electronic devices.

Part Description

The ADPL62086 is a supervisory circuit that monitors voltages ranging from 1.02V to 4.8V. It features a factory-set reset threshold, which ensures that the system resets when the monitored voltage exceeds its threshold. The component includes a manual reset (MR) input, allowing external logic circuits to initiate a reset when necessary. Additionally, it has an open-drain, active-low reset output that asserts during the reset timeout period after the voltage threshold is exceeded. The device operates efficiently with a low supply current of 5µA (typical) and is housed in a compact 4-lead SOT23 package, making it suitable for space-constrained applications.
