MAX809LEUR-T

The MAX809LEUR-T from MAXIM is a compact microprocessor supervisor designed to monitor power supply voltage and generate a reliable reset signal when the supply drops below a safe level. It features a fixed reset threshold of approximately 4.63V, helping protect processors and digital circuits from unstable power conditions. This device comes in a 3-pin SOT-23 package, making it suitable for space-constrained designs in embedded electronics. When the monitored voltage falls below the threshold, the supervisor asserts a reset signal and maintains it for a typical 140ms reset timeout period to allow the system to stabilize. The MAX809LEUR-T is commonly used in microcontroller systems, industrial electronics, communication equipment, and portable devices. With an operating temperature range of −40°C to +85°C, it supports reliable performance in demanding applications.
