Product Overview: MCP809M3X-4.38/NOPB

The MCP809M3X-4.38/NOPB is a highly reliable voltage supervisor component manufactured by Texas Instruments, designed to maintain system integrity through monitoring voltage levels. This microprocessor (µP) supervisory circuit is specifically engineered to keep a watchful eye on the power supply voltage of digital systems. When a power failure or dip occurs, it ensures that the system has enough time to save data and execute proper shutdown procedures by asserting a reset signal when the monitored voltage falls below the designated threshold.

Key Features

• Voltage Threshold: The device features a precise threshold voltage of 4.38V, tailored for applications that operate around this voltage level, ensuring that the system remains within operational parameters.
• Reset Timeout: It comes with a built-in delay before the reset signal is deasserted, allowing the power supply and processor to stabilize. This timeout period ensures reliable system reset and startup.
• Low Power Consumption: Designed for power-sensitive applications, the MCP809M3X-4.38/NOPB draws minimal current, which is a critical feature for battery-operated and portable devices.
• Operating Temperature: The device can operate over a wide temperature range, making it suitable for various environments and applications.
• Packaging: It is available in a compact SOT-23 package, which is ideal for space-constrained applications.
• Lead-Free and RoHS Compliant: The product adheres to environmental standards, being lead-free and compliant with the Restriction of Hazardous Substances (RoHS) directive.

Applications

The MCP809M3X-4.38/NOPB is versatile and can be used in a wide array of applications, including:

• Computers and computer peripherals
• Embedded systems
• Portable and battery-operated devices
• Industrial equipment
• Automotive systems

With its precision voltage monitoring and low power consumption, the MCP809M3X-4.38/NOPB from Texas Instruments is an essential component for systems where reliable voltage supervision is critical. Its compact form factor and robust feature set make it a go-to solution for designers looking to enhance system reliability and protection.
