Maxim Integrated MAX6707ASKA+T Microprocessor Supervisory Circuit

The MAX6707ASKA+T from Maxim Integrated is a versatile microprocessor (µP) supervisory circuit designed to monitor power supplies and µP activity in 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 processor supervision.

This component is particularly suitable for use in portable, battery-powered devices due to its low power consumption. The MAX6707ASKA+T supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The reset output remains asserted for a preset timeout period after V_CC has risen above the reset threshold level, providing a stable system reset.

Key features of the MAX6707ASKA+T include:

• Precision Monitoring: It offers precision voltage monitoring of +2.5V, +3V, +3.3V, and +5V power-supply voltages, making it highly adaptable to various system requirements.
• Low Power Consumption: With its low supply current of 5µA (typical), it is an energy-efficient solution for battery-operated devices.
• Adjustable Reset Timeout: The device features an externally adjustable reset timeout period, allowing designers to tailor the system reset characteristics to specific application needs.
• Manual Reset Input: A manual reset input is provided, enabling a reset to be triggered with an external push-button or logic signal.
• Compact Package: Its compact 8-pin SOT-23 package makes it ideal for space-constrained applications.

The MAX6707ASKA+T operates over a wide temperature range of -40°C to +125°C, ensuring reliable performance in various environments. With its integrated features, this supervisory circuit simplifies design, reduces component count, and enhances system reliability, making it a preferred choice for designers looking to improve their power management solutions.

Overall, the MAX6707ASKA+T is an excellent choice for applications requiring reliable voltage monitoring and processor supervision without the need for complex configurations or additional external components.
