The MAX815LCSA+ from Maxim Integrated is a highly reliable supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It provides a significant layer of protection by ensuring that the system's voltage levels remain within operational thresholds, thereby safeguarding the system against potential damage due to power surges, brownouts, or other voltage-related anomalies.

Key Features

• Precision Monitoring: This component is capable of precision monitoring of 3V, 3.3V, and 5V power-supply voltages, making it versatile for a wide range of applications.
• Power-On Reset: The MAX815LCSA+ generates a reset signal when the monitored power supply falls below the factory-set reset threshold. The reset signal remains asserted for a minimum of 140ms after the supply voltage exceeds the reset threshold, ensuring proper system reset.
• Manual Reset: A manual reset feature allows for an external push-button to initiate a system reset, providing an additional level of user control.
• Low Power Consumption: Designed with power efficiency in mind, this device consumes minimal power, making it suitable for battery-operated applications.
• Compact Package: The MAX815LCSA+ is available in a space-saving 8-pin SO package, ideal for systems where board space is at a premium.

Applications

The supervisory circuit is well-suited for a variety of applications, including:

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

Technical Specifications

The MAX815LCSA+ operates over a wide temperature range, from -40°C to +85°C, offering reliable performance across diverse environmental conditions. It features an active-low reset output, which is compatible with most microprocessors and digital systems. The device is also designed to ignore fast transients on the VCC line, reducing the likelihood of false resets due to noise and line disturbances.

Overall, the MAX815LCSA+ supervisory circuit from Maxim Integrated stands out for its precision voltage monitoring, robust feature set, and compact form factor, making it an excellent choice for enhancing system reliability and protection.
