The MAX810M-4.38 from Maxim Integrated is a compact, highly reliable voltage supervisor IC designed to monitor power supplies in microprocessor systems. It provides a precise, factory-trimmed voltage threshold of 4.38V, ensuring that your system operates within safe voltage levels. When the monitored voltage falls below the 4.38V threshold, the MAX810M-4.38 asserts a reset signal, helping to protect the system from improper operation.

This device is ideal for portable, automotive, and other voltage-sensitive applications where precise monitoring is crucial. The MAX810M-4.38 features a low power consumption, making it suitable for battery-operated devices. Its small size and ease of integration make it a popular choice among engineers and designers looking to incorporate voltage monitoring without adding significant bulk or complexity to their designs.

Key Features

• Factory-Set V<sub>CC Reset Threshold: A precise 4.38V threshold ensures reliable monitoring and system protection.
• Low Power Consumption: Ideal for battery-powered applications, reducing the overall energy footprint of the system.
• Active-Low RESET Output: The output remains low until the monitored voltage exceeds the reset threshold, ensuring a proper system reset.
• Manual Reset Input: Provides a manual reset feature, allowing for system resets independent of the voltage threshold.
• Immune to Short V<sub>CC Transients: Offers robust operation by ignoring brief dips in supply voltage, preventing unnecessary resets.

Applications

• Microprocessor/Controller Systems
• Portable/Battery-Powered Equipment
• Automotive Electronics
• Computers and Controllers
• Embedded Systems

In summary, the MAX810M-4.38 is a versatile and dependable solution for voltage supervision requirements. Its ease of use, combined with Maxim Integrated's reputation for high-quality components, makes it an excellent choice for safeguarding your electronic systems.
