Maxim Integrated MAX6831TZUT+T Microprocessor (µP) Supervisory Circuits

The Maxim Integrated MAX6831TZUT+T is a highly reliable, low-power microprocessor 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 battery-powered applications, portable equipment, and microprocessor-based systems.

Key Features

• Power Supply Monitoring: The MAX6831 ensures that the µP is held in reset until the system's power supply reaches a stable and accurate threshold, protecting the system from low voltage conditions.
• Manual Reset Input: A manual reset input is provided, allowing for a system reset to be generated on demand from an external source.
• Low Quiescent Current: This device is optimized for low power consumption, with a quiescent current of only 1.6µA, making it ideal for battery-operated applications.
• Factory-Set Reset Thresholds: The reset thresholds are preset at the factory, eliminating the need for external resistors and adjustments, simplifying design and ensuring repeatability between devices.
• Reset Timeout: The MAX6831 features a fixed reset timeout of 140ms (minimum), ensuring that the µP has sufficient time to initialize after power-up or during a brownout condition.
• Small Package: The device is available in a small, 3-pin SOT23 package, which saves space on PCBs and is suitable for space-constrained applications.

Applications

• Portable Devices
• Battery-Powered Equipment
• Notebooks and PDAs
• Embedded Systems
• Consumer Electronics
