PMIC - Supervisors are the lynchpin of any integrated circuit, as they provide direct power to the device and are vital in regulating the various nodes and signals in the device. ADM707AN is one such PMIC - Supervisors and it\'s well suited to a wide variety of applications, thanks to its reliable performance, advanced features and excellent design. This article will explain the application field and working principle of the ADM707AN.

The ADM707AN is a high-performance low-power PMIC - Supervisor with an advanced Fault Management System. This allows it to identify short circuit and over-current conditions and take corrective action. It is rated at up to +2.00V and can drive currents up to 2A. It is specially designed to provide reliable power supply to low-power systems, such as low power microcontroller (MCU) applications, non-volatile memory (NVM) applications, and automotive applications.

The ADM707AN also provides a wide range of programmability. It has selectable voltage monitoring threshold, programmable timeout levels, and programmable power-on reset delay. This allows users to customize the configuration to suit their own applications. In addition, the ADM707AN is compatible with the JEDEC standard voltage task list and can be configured to different output voltages depending on the user\'s needs.

The working principle of the ADM707AN is based on an integrated circuit that holds four comparators and a voltage reference. Each of the comparators is used to monitor the voltage of a power supply signal, and the voltage reference provides the nominal voltage for comparison. When the voltage of the signal falls outside of the tolerance window, the comparator triggers a signal, which then causes the ADM707AN to shut off the supply signal.

The ADM707AN also comes with a power reset (POR) function, which is used to reset the power supply signal if there is an over-voltage or over-current condition. The POR signal will reset the power supply, thereby allowing the system to recover from the adverse condition. Furthermore, the on-chip timer ensures that the POR signal will be triggered at the right time, allowing for a smooth recovery of the system.

In terms of robustness, the ADM707AN has an over-voltage protection (OVP) function that can detect voltage surges and shut down the system if it exceeds the specified limit. This helps to ensure that the system does not become vulnerable to external voltage surges. Furthermore, the ADM707AN can detect short circuit and over-current conditions, and it can take corrective action by shutting down the concerned supply signal.

Overall, the ADM707AN provides a great solution for many applications. Its advanced features, such as programmability, OVP, POR, and fault management system make it an attractive choice for low-power systems. Its reliable performance and excellent design make it suitable for a wide variety of applications, and it is one of the most reliable PMIC - Supervisors available in the market.
