The MAX6704MKA from Maxim Integrated is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a +2.5V, +3V, +3.3V, or +5V power supply voltage.

This supervisory circuit significantly enhances system robustness by providing several key features. It generates a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it active for a minimum of 140ms after VCC has risen above the reset threshold. This ensures that the µP is held in reset until the system power is stable.

Key Features:

• Precision Monitoring: The MAX6704MKA offers precision monitoring of +2.5V, +3V, +3.3V, and +5V power-supply voltages.
• Manual Reset Input: A manual reset input is provided, allowing for a reset to be triggered with an external push-button or logic signal.
• Low Power Consumption: This device features low supply current, making it suitable for battery-operated applications.
• Reset Timeout: It has an internally fixed reset timeout period of 140ms (min) that ensures proper system reset.
• Small Size: The MAX6704MKA comes in a compact 8-pin SOT23 package, ideal for space-constrained applications.

These features make the MAX6704MKA an ideal choice for portable devices, computers, controllers, and intelligent instruments. It offers a robust power supply monitoring system that can safeguard µP systems from uncertain power-up, brownout conditions, and power-down events.

Applications:

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

Maxim Integrated's MAX6704MKA is the go-to solution for designers looking for a simple, efficient, and reliable way to bolster the safety and stability of their microprocessor-based systems.
