The MAX6808SA46+T is a compact, highly reliable microprocessor (µP) supervisory circuit from Maxim Integrated, designed to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its reset function, ensuring that the µP resets to a known state during power-up, power-down, or brown-out conditions.

This device comes in a small 8-pin SO package, making it suitable for space-constrained applications. Operating over a wide voltage range, the MAX6808SA46+T offers versatility for various applications, including computers, controllers, intelligent instruments, and critical µP power monitoring.

Key Features

• Reset Threshold Voltage: Precisely set at 4.63V, this feature ensures reliable operation by monitoring the supply voltage and asserting a reset if it drops below this threshold.
• Low Power Consumption: With its low supply current draw, the device is an excellent choice for power-sensitive applications.
• Manual Reset Input: This input allows for a manual reset, enabling the user to trigger a system reset as needed.
• Reset Timeout: The MAX6808SA46+T provides a 140ms minimum power-on reset timeout period, which prevents the system from starting up during short transients or insufficient power-up conditions.
• Immunity to Short Vcc Transients: The device is designed to ignore brief glitches on the Vcc line, enhancing system stability.

Applications

• Computers and Servers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Industrial Controllers
• Intelligent Instruments
