Product Overview: LM809M3X-2.45/NOPB

The LM809M3X-2.45/NOPB is a highly reliable voltage supervisor component designed and manufactured by Texas Instruments, a leader in the semiconductor industry. This device is a microprocessor supervisory circuit used to monitor power supplies in digital systems; it provides a significant function by asserting a reset signal whenever the VCC supply voltage declines below a predetermined threshold, ensuring proper system operation during power-up, power-down, and brown-out conditions.

Key Features

• Voltage Threshold: The device has a preset threshold voltage of 2.45V, which is suitable for low-voltage applications that require precise voltage monitoring.
• Reset Time Delay: It features a built-in delay time which ensures that the system has stabilized before the microprocessor is allowed to run, preventing any erroneous operations during power fluctuations.
• Low Power Consumption: Designed for energy efficiency, the LM809M3X-2.45/NOPB is optimal for battery-powered devices, contributing to longer battery life and reduced power costs.
• Temperature Range: The device operates over an industrial temperature range, making it suitable for various applications, including harsh environments.
• Form Factor: It comes in a compact SOT-23 package, making it ideal for space-constrained applications.
• RoHS Compliant: The NOPB designation indicates that this product is lead-free and RoHS compliant, aligning with environmental standards and regulations.

Applications

The LM809M3X-2.45/NOPB is versatile and can be used in a wide range of applications. It is particularly useful in systems that require a reliable reset mechanism, such as:

• Portable/Battery-Powered Devices
• Microprocessor/Microcontroller Systems
• Computers and Computer Peripherals
• Embedded Systems
• Networking Equipment

With its precise voltage monitoring and low power consumption, the LM809M3X-2.45/NOPB is an essential component for designers looking to enhance system reliability and prevent data corruption due to power anomalies. Texas Instruments' commitment to quality ensures that this voltage supervisor meets the stringent requirements of modern electronic systems.
