PMIC - Supervisors is a type of power management integrated circuit that monitors and supervises a wide range of power supply and voltage related functions. ADM1816-5AKS-REEL7 is a type of PMIC - Supervisor. It is used for applications such as mobile platform power and reset management, connected microprocessor reset and power management, point of load power management and voltage monitoring. In this article, we will discuss its application fields and working principle.

6 Applications Fields of ADM1816-5AKS-REEL7

1. Mobile platform power and reset management

The ADM1816-5AKS-REEL7 is used in mobile devices and embedded systems. It provides power supply, supplies power-up initialization signals, and maintains low power states throughout operation. When a critical voltage drops below a predefined threshold, or when a fault condition is detected, it will immediately reset the system.

2. Connected microprocessor reset and power management

The ADM1816-5AKS-REEL7 is used for reset and power management of connected microprocessors. It ensures that the reset is asserted when a power failure reaches a certain threshold level. It can also detect a power surge and trigger a reset when necessary. The supervisor can also monitor the main power supply and the auxiliary power supply as well as switch between them when needed.

3. Point of load power management

The ADM1816-5AKS-REEL7 is used for power management at the point of load. It can regulate the amount of current delivered to different components of the system, such as processors and memories. It ensures that each component gets the optimum amount of current for optimal performance. It can also protect systems from over-current events.

4. Voltage monitoring

The ADM1816-5AKS-REEL7 is used to monitor voltages across the system. It can detect if a voltage is not within the acceptable voltage range and can issue a warning or issue a reset depending on the circumstances. It can monitor a wide range of voltages, such as main power supply voltage, core voltage, and other voltages.

5. Power supply sequencing

The ADM1816-5AKS-REEL7 is used for power supply sequencing. It can sequence multiple power supplies, such as AC to DC converters, in a predefined order. This ensures that each supply is active in the right order, ensuring a smooth transition and minimized disruption.

6. Power supply monitoring

The ADM1816-5AKS-REEL7 is also used for power supply monitoring. It can monitor the operating conditions of multiple power supplies and can detect over-current or over-voltage situations and extends system protection. It can also detect when the power supply needs to be reset.

Working Principle of ADM1816-5AKS-REEL7

The ADM1816-5AKS-REEL7 is an integrated circuit which has two main parts: the main power supply monitor and the reset circuit. The main power supply monitor monitors the main power supply voltage levels and provides an output voltage within an acceptable voltage range. If the voltage exceeds or drops below the acceptable level, it will issue a warning or a reset. The reset circuit monitors the system and provides a reset to the system if a critical voltage drops below a predefined threshold, or when a fault condition is detected.

The working of the ADM1816-5AKS-REEL7 is based on voltage regulation and fault detection. The supervisor detects and monitors the voltage levels across the system, and if it detects that the voltage is not within the acceptable range, it will issue an alert or reset the system. It can also detect over-current and over-voltage situations and can reset the system if needed. It can also sequence multiple power supplies in a predefined order and monitor the operating conditions of the power supplies.

In summary, the ADM1816-5AKS-REEL7 is an integrated circuit used for a wide range of power supply and voltage related applications. It is used for mobile platform power and reset management, connected microprocessor reset and power management, point of load power management, voltage monitoring, power supply sequencing, and power supply monitoring. It can detect faults and over-current situations, reset the system when needed, and sequence multiple power supplies.
