The MAX706CUA is a highly reliable, low-power microprocessor (µP) supervisory circuit, engineered by Maxim Integrated 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 system monitoring applications.

This supervisory circuit is designed to maintain system integrity through a variety of features. It includes a reset output during power-up, power-down, and brownout conditions. The reset signal remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, ensuring that the µP starts up in a known state every time. Additionally, the MAX706CUA includes a debounced manual reset input which allows for a very flexible reset activation.

The MAX706CUA comes in a compact 8-pin µMAX package, making it suitable for space-constrained applications. It operates over a wide voltage range from 4.5V to 5.5V, catering to a variety of digital systems. This device also features a low supply current of 17µA, making it ideal for portable and battery-powered equipment.

Key features of the MAX706CUA include:

• Precision monitoring of 5V power-supply voltages
• Fully integrated power-on reset circuit
• 140ms min power-on reset pulse width
• Debounced manual reset input
• Low supply current of 17µA
• Wide operating temperature range: -40°C to +85°C
• Compact 8-pin µMAX package

Applications for the MAX706CUA are diverse and include systems that require a reliable reset signal, such as computers, controllers, intelligent instruments, critical µP power monitoring, and portable/battery-powered equipment. Its ability to ensure a predictable system reset, regardless of VCC startup characteristics, makes it a go-to choice for designers looking to enhance system reliability without significantly increasing cost or complexity.

With Maxim Integrated's reputation for quality and performance, the MAX706CUA is a superior choice for system designers who require a dependable supervisory solution.
