ADM1810-10ARTZ-RL7

Power Management Integrated Circuits (PMICs) are one of the most important components used in a wide range of digital applications. Supervisors are a class of PMICs that help to maintain reliable operation of the system by detecting and responding to hazardous conditions and preventing them from causing further damage. The ADM1810-10ARTZ-RL7 is a microprocessor system supervisor (MSS) used in digital systems for managing power supplies and ensuring system stability. This article will cover the application field and working principle of the ADM1810-10ARTZ-RL7.

Application Area

The ADM1810-10ARTZ-RL7 is typically used to manage multiple power supplies in consumer electronic devices, such as televisions, computers and gaming consoles. It provides a one-stop solution for power management, and can be used to monitor and control the voltage of each power rail, detect faults on power supplies and provide over-current and over-power protection. Moreover, it also includes a watchdog timer for system reset, thermal protection and low power detection, offering a complete PMIC solution.

Working Principle

The ADM1810-10ARTZ-RL7 primarily monitors the voltages on up to eight power rails. It senses any voltage variations and generates a reset signal accordingly via a watchdog timer if needed. It also comes with a low current power-on reset (POR) circuit, which will reset the system if the input voltage is detected below the minimum operating level. This ensures that the system’s performance is not affected by abrupt voltage drops or spikes. Additionally, it provides a built-in programmable over-current protection (OCP) circuit to protect power supplies from over-current loads. It can also activate the protection circuit when the power consumption of the system exceeds the set threshold. Finally, the ADM1810-10ARTZ-RL7 also features a thermal protection function. When internal die temperature exceeds the pre-programmed trigger point, it will shut down the power supply to prevent potential damage.

Conclusion

The ADM1810-10ARTZ-RL7 is an ultra-low power supervisor designed to directly monitor the voltages of up to eight power rails. It offers reliable over-voltage, over-current and thermal protection, while allowing flexible configurability. The ADM1810-10ARTZ-RL7 is an ideal power management solution for consumer electronics applications.
