The DS1818R-5+T&R from Maxim Integrated is a highly efficient microprocessor (µP) supervisory circuit designed to monitor the power supplies in µP and digital systems. It provides a crucial function by ensuring that the µP boots up in a predictable state every time. This component is essential for maintaining system integrity during power-up, power-down, and brown-out conditions.

Key Features

• Precision Monitoring: The device features a precise factory-trimmed threshold that monitors the +5V power supply voltage, ensuring reliable operation of the system.
• Reset Signal: Upon detecting an out-of-tolerance condition, the DS1818 asserts a reset signal to the µP, holding it in reset for a minimum of 350ms after the supply voltage returns to an acceptable level, providing the system ample time to stabilize.
• Low Power Consumption: With its low power consumption, this circuit is an ideal choice for power-sensitive applications.
• Compact Packaging: The DS1818R-5+T&R is available in a space-saving SOT-23 package, making it suitable for use in systems where space is at a premium.
• Temperature Range: It operates over a wide temperature range, making it versatile for various environmental conditions.

Applications

The reset circuit is commonly used in applications such as:

• Computers and servers
• Embedded systems
• Portable/battery-powered equipment
• Industrial controllers
