Maxim Integrated Product: MAX817MCSA+T

The MAX817MCSA+T is a high-performance microprocessor (µP) supervisory circuit designed 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 battery-powered applications. This device is particularly suitable for use in portable computers, controllers, and intelligent instruments where efficient power monitoring is crucial.

Key Features:

• Precision Monitoring: The MAX817MCSA+T offers precise monitoring of +3V, +3.3V, and +5V power-supply voltages to ensure that the system is operating within acceptable limits.
• Power-On Reset: It features a power-on reset input with a significant delay (200ms minimum), which provides a reliable system reset to the microprocessor during power-up, power-down, and brown-out conditions.
• Manual Reset: A manual reset input allows for a reset to be triggered with an external switch or logic signal, providing additional system control and diagnostic capabilities.
• Voltage Monitoring: The device includes a debounced TTL/CMOS-compatible manual-reset input and monitors the reset outputs from the µP for both push-pull and open-drain configurations.
• Compact Package: Packaged in a compact 8-pin SOIC, the MAX817MCSA+T occupies minimal board space, making it ideal for space-constrained applications.

Applications:

• Computers and Servers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Intelligent Instruments
• Industrial Controllers

The MAX817MCSA+T is a versatile and reliable solution for system power supply monitoring. It ensures that the system microprocessor always starts up in a known state and helps prevent code execution errors during low-voltage conditions. This supervisory circuit is a testament to Maxim Integrated's commitment to providing innovative, high-quality products for power management applications.

Whether you are designing a new system or looking to improve the reliability of an existing one, the MAX817MCSA+T by Maxim Integrated offers a robust feature set that can help simplify your design and enhance system integrity.
