Maxim Integrated DS1813-5/TR MicroMonitor Chip

The Maxim Integrated DS1813-5/TR is a highly reliable and versatile microprocessor (µP) supervisory circuit that ensures the proper functioning of µP systems by monitoring the power supply. It is an essential component for systems that require an automatic restart and controlled operation during power-up, power-down, or brown-out conditions. The DS1813-5/TR is designed to keep your microprocessor-based systems secure and efficient, making it an ideal choice for a wide range of applications, including computers, controllers, and intelligent instruments.

This MicroMonitor chip comes in a three-pin, transistor-to-transistor logic (TTL) compatible, reset-only configuration. It operates over a wide voltage range and offers a precise monitoring option for 5V-powered systems. The DS1813-5/TR variant specifically has a preset threshold voltage of 4.63V, which is critical in detecting out-of-tolerance power supply conditions and asserting a reset signal to the µP, ensuring the system boots up in a known state every time.

Featuring a built-in delay, the DS1813-5/TR provides a reset signal for a minimum of 150ms after the supply voltage exceeds the reset threshold level. This delay ensures that the µP and the system have adequate time to stabilize before starting operations. The chip's active-low reset output guarantees compatibility with most µP and microcontroller (MCU) systems, providing a straightforward integration into your design.

For added convenience, the DS1813-5/TR is available in a compact SOT-23 package, making it suitable for space-constrained applications. Its low power consumption and high precision make it an economical choice for managing power supply conditions in your electronic systems.

Maxim Integrated's commitment to quality ensures that the DS1813-5/TR MicroMonitor chip offers outstanding reliability, providing your projects with a robust power management solution that you can depend on. Whether you're designing new systems or upgrading existing ones, the DS1813-5/TR offers the protection and performance you need for smooth and safe operations.
