MAX811TEUS+T General Description

The MAX811/MAX812 are low-power microprocessor (µP) supervisory circuits used to monitor power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered or 3V-powered circuits. The MAX811/MAX812 also provide a debounced manual reset input.

Key Features

Integrated Voltage Monitor Increases System Robustness with Added Manual Reset
- Precision Monitoring of 3V, 3.3V, and 5V Power-Supply Voltages
- 140ms Min Power-On-Reset Pulse Width
  - - Active-Low RESET Output (MAX811), RESET Output (MAX812)
- Guaranteed Over Temperature
- Guaranteed Active-Low RESET Valid to V_CC = 1V (MAX811)
- Power-Supply Transient Immunity
Saves Board Space
- No External Components
- 4-Pin SOT143 Package
Low Power Consumption Simplifies Power-Supply Requirements
- 6µA Supply Current
