Maxim Integrated DS1233DZ-15+ Product Overview

The Maxim Integrated DS1233DZ-15+ is a robust, precision microprocessor supervisory circuit designed to monitor the power supplies in microprocessor and digital systems. It provides a crucial function by ensuring that the system's microprocessor starts up in a predictable state every time the system's power is turned on or restored after a fault. This device is essential for maintaining system reliability and preventing data corruption in the event of power anomalies.

The DS1233DZ-15+ operates by monitoring the system's supply voltage. When this voltage drops below a preset threshold, the device asserts a reset signal, which holds the microprocessor in a reset state until stable power is detected. The reset signal remains asserted for a minimum of 150ms after the supply voltage exceeds the reset threshold, ensuring that the microprocessor restarts with a clean slate.

Featuring a nominal threshold voltage of 4.375V, the DS1233DZ-15+ is suitable for 5V-powered systems. It offers a tight threshold accuracy and low power consumption, making it an excellent choice for portable and low-power applications. The device comes in a compact, 3-pin TO-92 package, which makes it easy to integrate into existing designs without significant layout changes.

Additional features of the DS1233DZ-15+ include:

• An active-low RESET output, which is guaranteed to be in the correct state for VCC down to 1V.
• Immunity to short VCC transients, ensuring reliable operation even in noisy environments.
• Low cost and high reliability, with no external components required for operation.

As a product of Maxim Integrated, a trusted leader in the design, manufacturing, and supply of high-performance semiconductor products, the DS1233DZ-15+ is built to the highest quality standards. It is ideal for use in a wide range of applications, including computers, controllers, intelligent instruments, critical microprocessor power monitoring, and portable battery-powered equipment.

Whether you're designing a new system or looking to enhance the reliability of an existing one, the DS1233DZ-15+ offers a simple and effective solution for microprocessor supervision and power management.
