The DS1813-10 is a robust and reliable economizer reset IC from Maxim Integrated that provides an efficient solution for system monitoring and protection. Designed with precision, this device offers a cost-effective way to ensure your system remains operational under various conditions.

The DS1813-10 operates by monitoring the supply voltage of a microprocessor (μP) or digital system. It asserts a reset signal whenever the V<sub>CC supply voltage declines below a preset threshold, ensuring that the μP initializes in a known state. The reset signal remains asserted for a minimum of 150ms after V<sub>CC rises above the reset threshold, providing ample time for the system to stabilize.

This economizer reset IC is tailored for a nominal threshold voltage of 4.37V, which is suitable for 5V-powered systems. It is an ideal choice for applications that require a high level of reliability and precision, such as embedded systems, servers, and telecommunications equipment.

The DS1813-10 comes in a compact, 3-pin TO-92 package, which makes it easy to integrate into existing designs without requiring significant board space. Its low power consumption and wide operating temperature range from -40°C to +85°C ensure that it performs reliably in a variety of environments and applications.

Key features of the DS1813-10 include:

• Automatically restarts a microprocessor after power failure
• Maintains reset for 150ms after V<sub>CC becomes valid to stabilize the system
• Accurate 5% or 10% microprocessor power supply monitoring
• Operates from -40°C to +85°C temperature range
• Low cost and small size

In summary, the Maxim Integrated DS1813-10 is a dependable and economical solution for system reset requirements. Its ability to ensure a proper startup sequence for digital systems makes it a valuable component in preventing system failures and preserving data integrity.
