The MAX6344RUT-T from Maxim Integrated is a robust, low-power 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 portable consumer, computing, and industrial applications.

Key Features

• Precision Monitoring: This device features a precision factory-set V_CC reset threshold and offers a ±1.5% reset threshold accuracy over the entire temperature range, ensuring reliable monitoring and system protection.
• Low Power Consumption: The MAX6344RUT-T is optimized for low-power operations, making it ideal for battery-powered equipment. Its quiescent current is only 1.2µA at V_CC = 1.2V, which helps extend battery life.
• Manual Reset Input: A manual reset input is provided, allowing for a system reset to be triggered with an external push-button or logic signal for increased system control.
• Watchdog Timer: An on-board watchdog timer ensures that the system microcontroller is operating correctly. If the microcontroller fails to provide a watchdog pulse within a preset timeout period, the MAX6344RUT-T will assert a system reset.
• Power-On Reset: The device generates a reset signal upon power-up, holding the connected microprocessor in reset until conditions have stabilized, ensuring a clean start for the system.
• Small Form Factor: The component is available in a tiny, 6-pin SOT-23 package, which is suitable for space-constrained applications.

Applications

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Data Storage Equipment
• Industrial and Automotive Systems

The MAX6344RUT-T supervisory circuit is a reliable solution for systems that require constant monitoring of the power supply voltage. It ensures that the system microprocessor always starts up in the same state and helps prevent code execution errors during power-up, power-down, and brown-out conditions.
