The DS1813-10/T&R is a 5V EconoReset voltage monitor manufactured by Rochester Electronics. It's designed to monitor the power supply voltage of microprocessors, microcontrollers, and other digital systems, providing a reset signal when the voltage falls below a specified threshold.

Applications:

• Microprocessor reset circuits
• Microcontroller reset circuits
• Power-on reset circuits
• Battery monitoring
• Voltage monitoring in embedded systems

Features:

• Precision voltage monitoring
• Active-low reset output
• Fixed reset threshold (4.62V)
• Short reset pulse width (140ms minimum)
• Small package (TO-92)

Benefits:

• Prevents system crashes by ensuring proper reset of the microprocessor or microcontroller during power-up or brownout conditions.
• Simple and cost-effective voltage monitoring solution.
• Guaranteed reset performance with a fixed reset threshold.
• Reliable reset signal generation even with short power interruptions.
• Compact size suitable for space-constrained applications.

Additional Details:

The DS1813-10/T&R features a precise internal voltage reference to accurately monitor the 5V supply. When the supply voltage drops below the reset threshold of 4.62V, the active-low reset output is asserted, signaling the microprocessor to reset. The reset output remains asserted for a minimum of 140ms after the supply voltage recovers above the threshold, ensuring a clean reset. The device operates over a temperature range of -40°C to +85°C. It is commonly used in industrial control systems, consumer electronics, and automotive applications to ensure reliable operation of digital circuits. The TO-92 package allows for easy through-hole mounting on circuit boards. The device is available in tape and reel packaging for automated assembly.
