Power management IC (PMIC) is an integrated circuit (IC) that is used to provide power to digital systems such as microcontrollers, digital signal processors, and programmable logic controllers. It handles the conversion, regulation, and voltage monitoring of the system\'s power supply, usually taking a Vcc power supply voltage and creating several adjustable, regulated voltages suitable for various digital devices. The ADM6315-31D2ART-RL is a 32-pin supervisory IC designed to manage and protect the system\'s power supply.

ADM6315-31D2ART-RL is a IC package that is specifically designed for low-voltage systems. It is an active low voltage supervisor IC that is used for system reset and power-on monitoring. It is integrated with a built-in voltage detector, active-low reset output, brown-out input, system power-on monitoring output, active high voltage supply output, and reset delay timer. Due to its features, the ADM6315-31D2ART-RL is ideally suited for applications such as power sequencing, battery monitoring and controlled system power-on.

The ADM6315-31D2ART-RL is also well suited for other applications in 3.3V, 2.5V, 1.8V and 1.2V systems.

Working Principle

The ADM6315-31D2ART-RL contains several components that work together to provide power monitoring and reset functions. At the heart of this IC is a voltage detector and comparator that monitors an external supply voltage. This voltage detector is set to a pre-determined voltage level by the user, and when the detected voltage falls below this level, the comparator triggers the reset output signal line. This reset signal can be used to reset the system, protecting the system from being damaged by an inadequate supply voltage.

In addition to the reset output, the controller also has a voltage supply output that provides an active high output voltage to power the processor and other digital components. The ADM6315-31D2ART-RL is also equipped with a reset delay timer, which keeps the reset signal active for a period of time after the voltage falls below the pre-determined level. This prevents the system from resetting too often, and allows the supply voltage to come back up to acceptable levels before resetting.

The ADM6315-31D2ART-RL also has a brown out input which is used to detect sudden drops in the supply voltage. When the brownout voltage is detected, the reset output is triggered and the reset delay timer is activated. The brownout function can be used to prevent the system from resetting during a power surge.

Finally, the controller also has a system power-on monitoring output which can be used to monitor the system to ensure that the power supply is within acceptable levels. The system power-on output is active high when the supply voltage is within acceptable levels, and active low when the supply voltage drops below the pre-determined level.

The ADM6315-31D2ART-RL is an extremely versatile IC which is capable of providing a wide range of features for power monitoring and reset functions. It is an ideal solution for embedded systems requiring system reset protection and voltage monitoring.
