The MAX815NCSA+T from Maxim Integrated is a high-performance 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 with 5V-powered circuits.

Key Features

• Power Supply Monitoring: This component ensures that the µP is only operational when the power supply is within an acceptable range. It provides a reset output during power-up, power-down, and brownout conditions.
• Reset Timeout: The device features a preset timeout delay, which guarantees a minimum reset pulse width of 140ms, ensuring reliable system reset.
• Voltage Monitoring: The MAX815NCSA+T actively monitors the voltage level and asserts a reset signal if it detects a voltage that is out of threshold, helping to protect the µP and associated circuitry.
• Low Power Consumption: Designed for power-sensitive applications, it consumes minimal power, which is critical for battery-operated devices.
• Compact SOT Package: The device is available in a space-saving 8-pin SOT23 package, making it suitable for use in systems where space is at a premium.

Applications

The MAX815NCSA+T is versatile and can be used in a variety of applications, including:

• Computers and Controllers
• Embedded Systems
• Portable/Battery-Powered Equipment
• Intelligent Instruments
• Critical µP Power Monitoring
