Product Overview: LM810M3X-4.00/NOPB

The LM810M3X-4.00/NOPB is a robust, precision microprocessor supervisory circuit designed and manufactured by Texas Instruments. This device is engineered to monitor the system voltage in microprocessor-based systems, providing a significant layer of protection against low voltage conditions, which can lead to system failure or malfunction. With its compact SOT-23 package, the LM810M3X-4.00/NOPB is an ideal choice for space-constrained applications.

This supervisory circuit is particularly well-suited for battery-powered electronics, where maintaining the correct operation voltage is crucial. It features a fixed sense threshold voltage of 4.00V, which ensures that the connected microprocessor or system is reset accurately and reliably when the monitored voltage falls below this specified threshold. The product comes with a built-in delay feature, which prevents nuisance resets by providing a delay time after the voltage drops before issuing a reset signal.

The LM810M3X-4.00/NOPB offers an active-low reset output, which remains asserted until the system voltage recovers and stabilizes above the threshold level for the preset delay time. This supervisory circuit boasts a low supply current, making it highly energy-efficient and suitable for portable devices where power conservation is critical.

Key features of the LM810M3X-4.00/NOPB include:

• Precision voltage monitoring
• Fixed threshold voltage: 4.00V
• Low supply current for energy efficiency
• Active-low reset output
• Built-in delay for avoiding false resets
• Compact SOT-23 package for space-saving design
• Lead-free and RoHS compliant
• Operating temperature range: -40°C to +85°C

As a product from Texas Instruments, the LM810M3X-4.00/NOPB is backed by the company's reputation for high-quality and reliable semiconductor products. This supervisory circuit is suitable for a variety of applications, including portable devices, computers, embedded systems, and critical microprocessor monitoring tasks. Its industry-standard packaging and pinout make it a versatile choice for design engineers looking to enhance system reliability and performance.

The "NOPB" suffix in the product code indicates that the LM810M3X-4.00/NOPB is provided in an environmentally friendly, lead-free package, complying with both RoHS and Green Product requirements. This makes it an excellent choice for companies and developers aiming to create eco-conscious electronic products.
