DS1815-20

PMIC (Power Management Integrated Circuit) - Supervisors are advanced integrated circuit solutions that are designed to provide increased accuracy and improved safety features to ensure the clean and reliable operation of electronic systems. One such product from the PMIC portfolio is the Maxim Integrated DS1815-20. This supervisor offers comprehensive system protection for operation in both industrial and consumer applications. It offers a range of additional features, including low quiescent current and low power consumption, which make it ideal for applications that require reduced power consumption.

The DS1815-20 integrates a Watchdog Timer, Power-On Reset, Reset Delay Circuit, 16-Bit Free Running Counter, and an integrated power supply regulator. The Watchdog Timer includes an adjustable delay between 0ms and 20s. This feature offers a wide range of protection against system failure by resetting the system if it fails to respond in time. Additionally, the DS1815-20 has an integrated Reset Delay Circuit, which activates on power-up to guarantee that the system is stable before the microcontroller begins execution.

Aside from its Watchdog Timer, the DS1815-20 also offers additional protection features such as an adjustable over-temperature protection circuit, low-battery monitor, and an adjustable over-current protection circuit. These three features protect the system from thermal and electrical overloads, preventing system damage or shutdown. While the over-temperature protection circuit detects excessive internal temperature inside the system, the over-current protection circuit monitors the electrical consumption of the system and provides a warning message when the consumption is too high.

In addition to its protection features, the DS1815-20 also offers comprehensive system monitoring. The integrated 16-bit free running counter monitors system activity, allowing users to view and log system events or errors. This feature is perfect for applications that require a detailed audit of system operations. Furthermore, the integrated power supply regulator allows the system to be powered from either a 12V or 24V DC power source, making it suitable for a range of industrial and consumer applications.

Overall, the Maxim Integrated DS1815-20 is an impressive device for operation in both industrial and consumer applications. Its low quiescent current and power consumption, along with its comprehensive protection and monitoring features, make it a superior choice for reliable safety and performance. The device is suitable for a wide range of applications and offers all the essential features for accurate and dependable system operation.
