The DS1233AZ-15+ is a sophisticated power supply monitor and microprocessor supervisory circuit designed by Maxim Integrated, a leader in the development of innovative analog and mixed-signal products. This particular device is engineered to enhance the reliability and correct operation of a microprocessor (µP) system, ensuring that the system operates optimally under various power conditions.

The DS1233AZ-15+ actively monitors the power supply voltage of a µP system. When the voltage drops below a precisely defined threshold, the device generates a reset signal to the µP. This reset signal is maintained for a minimum of 150ms after the supply voltage exceeds the reset threshold voltage. This feature ensures that the µP and its associated circuitry are reset properly, thereby preventing code execution errors due to insufficient power supply during startup, brownout, or power failure conditions.

Key Features:

• Precision Monitoring: The device provides precise monitoring of the 5V power-supply voltage with a 4.625V threshold, suitable for systems that require a high level of voltage accuracy.
• Automatic Reset: It generates an automatic reset pulse when the power supply voltage drops below the reset threshold.
• Low Power Consumption: The DS1233AZ-15+ is designed for low power consumption, making it ideal for power-sensitive applications.
• Wide Operating Temperature: It operates over a wide temperature range, from -40°C to +85°C, ensuring reliable performance in various environmental conditions.

The DS1233AZ-15+ comes in a compact 3-pin TO-92 package, which makes it easy to integrate into a wide range of system designs without occupying significant board space. Its simplicity of use, combined with its robust feature set, makes it an excellent choice for managing power supply functions in complex electronic systems.

Overall, the DS1233AZ-15+ from Maxim Integrated is a crucial component for any design that demands a high level of protection against power supply inconsistencies, ensuring that microprocessor systems remain functional and reliable under all circumstances.
