The DS1813R-5+T&R from Maxim Integrated is a highly reliable, precision microprocessor supervisory circuit designed to monitor the supply voltage of microprocessor (µP) systems. It provides a cost-effective solution for systems that require protection against power faults, ensuring that all operations are carried out safely and effectively.

Key Features

• Voltage Monitoring: This device actively monitors the VCC for undervoltage conditions during system power-up and operation. With a factory-trimmed reset threshold of 4.63V, it ensures that the µP and other critical components operate within safe voltage levels.
• Reset Timeout: The DS1813R-5+T&R generates a reset signal for a minimum of 350ms after VCC has risen above the reset threshold. This provides ample time for the system to stabilize before the processor begins operation.
• Temperature Range: It operates over a wide temperature range, making it suitable for various industrial applications. The device can function effectively in environments ranging from -40°C to +85°C.
• Form Factor: The component comes in a compact SOT-23 package, which is ideal for space-constrained applications without compromising performance and reliability.
• Power Supply: It supports a supply voltage range that typically spans from 1.2V to 5.5V, giving designers flexibility in various system configurations.
