The MAX6705ATKA+T from Maxim Integrated is a high-performance 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 that require voltage monitoring and battery control.

Key Features

• Voltage Monitoring: This device offers precision monitoring of 2.5V, 3V, 3.3V, and 5V power-supply voltages, ensuring that the system operates within safe voltage thresholds.
• Reset Output: The MAX6705ATKA+T has an active-low reset output which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold. This feature ensures that the µP and other critical components have sufficient time to initialize properly during power-up, power-down, or brownout conditions.
• Low Power Consumption: Designed for power-sensitive applications, this supervisory circuit consumes minimal power, with a typical supply current of only 17µA.
• Manual Reset Input: The inclusion of a manual reset input allows for a system reset to be triggered with an external switch or logic signal, providing additional flexibility and control for system diagnostics or troubleshooting.
• High Threshold Accuracy: With a ±1.5% reset threshold accuracy over the entire temperature range, the MAX6705ATKA+T ensures reliable operation even under varying environmental conditions.

Applications

The MAX6705ATKA+T is suited for a wide array of applications, particularly where precise voltage monitoring is critical. It is commonly used in:

• Computers and Servers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Data Storage Equipment
• Telecommunication Systems

Package and Availability

The device is available in a small 8-pin SOT23 package, which is ideal for space-constrained applications. The MAX6705ATKA+T is also provided in tape and reel form, facilitating efficient assembly for high-volume production. Its extended temperature range of -40°C to +125°C makes it suitable for industrial applications.

Maxim Integrated's commitment to quality and reliability is evident in the MAX6705ATKA+T, making it a smart choice for system designers who require a robust voltage monitoring solution.
