Maxim Integrated DS1233Z-15+ MicroMonitor Chip

The Maxim Integrated DS1233Z-15+ is a highly reliable, compact microprocessor supervisory circuit designed to monitor the power supplies in digital systems. It provides a significant level of protection against unpredictable system behavior caused by power failures or low voltage conditions. This device is a crucial component for maintaining the integrity of electronic systems, ensuring that microprocessors and other sensitive logic circuits are reset properly during power-up, power-down, or brown-out conditions.

The DS1233Z-15+ operates by monitoring the system voltage and holding the microprocessor in the reset state until that voltage reaches and remains at a stable and acceptable level for correct operation. With a preset threshold voltage of 4.625 volts, it is specifically tailored for 5V systems. Once the power supply exceeds this threshold, the DS1233Z-15+ keeps the reset output active for approximately 150ms after the voltage becomes stable, providing enough time for the system's power supply and processor to stabilize.

This device is available in a compact 3-pin TO-92 package, making it suitable for space-constrained applications. The DS1233Z-15+ is also characterized for operation over a full industrial temperature range (-40°C to +85°C), offering reliable performance in diverse operating conditions. Its low power consumption and high precision make it an excellent choice for portable and battery-operated equipment.

Key features of the DS1233Z-15+ include:

• Automatic reset generation during power-up, power-down, and brown-out conditions.
• Guaranteed reset valid to Vcc = 1V.
• 150ms (min) power-on reset pulse width.
• Low cost and low power consumption.
• No external components needed.
• TO-92 package for easy integration into existing designs.

The Maxim Integrated DS1233Z-15+ MicroMonitor Chip is a reliable and essential component for system designers looking to enhance the operational stability of their digital systems. Its ease of use and robust feature set make it an ideal choice for a wide range of applications in computing, consumer electronics, and industrial control systems.
