Maxim Integrated DS1233MS-3+T&R Overview

The DS1233MS-3+T&R is a robust microprocessor supervisory circuit from Maxim Integrated, designed to monitor the power supplies in microprocessor and digital systems. It provides a precise way to ensure that the microprocessor boots up in a predictable state every time. This device is essential for maintaining system integrity during power-up, power-down, and brown-out conditions.

Key Features

• Power Supply Monitoring: The DS1233MS-3+T&R actively monitors the system's power supply voltage levels, ensuring that the microprocessor has a stable and adequate supply for operation.
• Reset Signal: Upon detecting an out-of-tolerance power supply condition, the device generates a reset signal to the microprocessor, holding it in reset for a minimum of 250ms after the power supply has returned to an acceptable level. This ensures proper system reset and start-up.
• Low Standby Current: The device has been engineered to have a low standby current, which is critical for battery-operated devices where power conservation is paramount.
• High Accuracy: It offers high threshold accuracy (±5% over temperature), which is vital for reliable operation under varying conditions.
• Temperature Range: The DS1233MS-3+T&R operates over a wide temperature range, making it suitable for industrial applications.
• Compact Package: It is available in a compact surface-mount package, ideal for space-constrained applications.
• Tape and Reel: The ‘T&R’ suffix indicates that this product is delivered in tape and reel packaging, which is suitable for automated pick-and-place manufacturing processes, enhancing production efficiency.

Applications

The DS1233MS-3+T&R is versatile and can be integrated into a variety of systems, including:

• Computers and servers
• Embedded systems
• Communication devices
• Portable/battery-powered equipment

With its ability to ensure a safe system start-up and operation through effective power monitoring and reset functions, the DS1233MS-3+T&R from Maxim Integrated is an indispensable component for system designers looking to enhance reliability and performance in their digital systems.
