Description

The Maxim Integrated DS1818R-5+T is a highly reliable microprocessor (μP) supervisory circuit designed to monitor power supplies in μP and digital systems. It provides a crucial function by detecting out-of-tolerance power supply conditions and resetting the μP when necessary, thereby ensuring proper system operation upon power-up or during adverse voltage conditions.

Key Features

  • Precision Monitoring: The device features a precise factory-trimmed threshold voltage that ensures accurate monitoring of the V<sub>CC.
  • Low Power Consumption: With its low power design, the DS1818 consumes minimal power, making it suitable for power-sensitive applications.
  • Reset Time Delay: The built-in delay ensures the μP has sufficient time to initialize after power stabilizes, with a typical delay of 350ms.
  • Push-Pull Active-Low Reset Output: The device provides an active-low reset signal with a push-pull output, eliminating the need for an external pull-up resistor.
  • Temperature Range: It operates over a wide temperature range, from -40°C to +85°C, accommodating various environmental conditions.
  • Compact Package: The DS1818 is offered in a space-saving SOT-23 package, which is ideal for space-constrained applications.

Applications

The DS1818R-5+T is versatile and can be used in a wide array of applications where reliable system operation is critical. These include:

  • Computers and Servers
  • Embedded Systems
  • Portable/Battery-Powered Equipment
  • Network and Telecommunications
  • Industrial Controllers

Technical Specifications

The DS1818R-5+T operates with a nominal supply voltage (+V<sub>TRIP) of 5.0V, making it suitable for standard 5V logic systems. The active-low reset output ensures compatibility with most μP systems, and its push-pull configuration provides a robust signal without the need for external components.

For electronic system designers looking for a reliable reset circuit to safeguard their microprocessor-based systems, the Maxim Integrated DS1818R-5+T offers a compact, efficient, and precise solution that ensures system stability and a proper startup sequence.
