Key Features

The MAX811SEUS+T is a compact, low-power supervisory circuit designed to monitor supply voltage and assert a reset signal when necessary. It offers a 4.38 V threshold ideal for 5 V systems and provides a fixed 140 ms reset delay to ensure system stability upon power-up or voltage dips. The push-pull active-low output enables direct connection to digital logic without additional components. Its ultra-low quiescent current makes it ideal for battery-powered applications. Additionally, its space-saving SOT-143 package simplifies PCB layout in tight spaces.

Applications

Industrial control modules
Battery-operated devices
Networking and telecom systems
Set-top boxes
Embedded microcontroller systems
Point-of-sale terminals
Consumer electronics
Medical handheld devices
Data collection equipment
Power supply sequencing circuits

Product Overview

The MAX811SEUS+T offers a reliable solution for system voltage monitoring and reset control. Designed for compact embedded systems, it monitors the VCC line and triggers a reset whenever the voltage drops below 4.38 V. This ensures that microprocessors and logic systems reboot into a stable state, preventing erratic behavior or data corruption. Because it consumes minimal power and comes in a small form factor, it is ideal for both portable electronics and industrial control environments. Its predictable 140 ms delay provides sufficient time for power rails to stabilize before releasing the reset.
