Maxim Integrated's MAX16059ATT32+ Supervisory Circuit

The MAX16059ATT32+ is a highly efficient, low-power supervisory circuit designed by Maxim Integrated to monitor single or multiple system supply voltages. This compact component is essential for ensuring reliable operation in microprocessor and digital systems, where it provides excellent circuit protection and monitoring capabilities.

Encased in a small 6-pin TDFN package, the MAX16059ATT32+ is engineered to supervise voltages as low as 1.575V and as high as 5.0V with a factory-set threshold voltage of 3.2V, making it highly versatile for a range of applications. The device features a manual reset input, allowing the user to initiate a system reset, and a reset output, which can assert a reset signal to the system when any of the monitored supply voltages fall below the configured thresholds.

One of the key benefits of the MAX16059ATT32+ is its low quiescent current draw, typically 1.6µA, which is ideal for battery-operated and portable applications where power conservation is crucial. Additionally, the supervisory circuit includes an integrated watchdog timer that helps prevent system lock-up by resetting the system if the software becomes unresponsive.

The device offers a variety of features that enhance system reliability, including:

• Immunity to short voltage transients
• Low-power reset signal with adjustable delay
• Watchdog timer with a 1.6-second nominal timeout period
• Over-temperature protection

The MAX16059ATT32+ is suitable for a wide array of applications across different sectors, including:

• Computers and servers
• Consumer electronics
• Industrial control systems
• Telecommunications equipment

With its robust design and comprehensive voltage monitoring capabilities, the MAX16059ATT32+ from Maxim Integrated is an ideal choice for designers looking to enhance system stability and protect against power supply anomalies. Its compact footprint and precision voltage monitoring make it an indispensable component in modern electronic systems.
