The ADM811SART-REEL is an Advanced Microcontroller Bus Architecture (AMBA) Peripheral Management Interrupt Controller (PMIC) designed to monitor, control, and protect various levels of peripherals in computer and communications systems including laptops, desktops, and microcontrollers. It is designed to provide reliable operation across a wide range of operating conditions, from low-voltage to high-temperature applications, for solutions where space and power are especially limited.

The ADM811SART-REEL is a dual supervisory Chip Enable (CE) and Reset (RE) Supervisor. Within the system, it monitors the power supply, and issues a reset to other system elements like processor, FPGA, or ASIC when the power supply drops below a certain threshold, or when an externally provided signal drops below the chip\'s input threshold. The supervisor also has two CE outputs which can be used to control the device states of multiple internal bus elements such as I/O functions and power utilization.

The ADM811SART-REEL is able to work in both active and standby mode, providing enhanced system control experience. In active mode, the supervisor monitors two power supply rails, and when either one drops below the configured threshold, the supervisor sends an alarm signal to notify the system for automatic shut off. This avoids unnecessary power consumption and helps prevent system damage. On the other hand, in standby mode, the chip can continue to detect input signals over the configured threshold, and when an externally provided signal drops below the chip\'s input threshold, the chip sends a reset to the system. This relieves the user from the hassle of manually switching into standby mode and guarantees system stability.

In order to ensure that the ADM811SART-REEL produces the best performance in the system, users will need to configure it with the appropriate parameters. This includes setting up the internal registers to set the proper supply voltage, input thresholds and watch dog timeout parameters. The output pins used for reset, CE and IEEE/IEC power-on reset signaling also need to be specified. By configuring the AHB as a master, the chip can directly monitor and control various system elements such as processors, FPGAs and ASICs.

In addition to its use as a PMIC supervisor, the ADM811SART-REEL can provide several additional functions for system elements. These include hang detection, watchdog timer, glitch protection, power-saving power selector, supply voltage monitoring, and power on/off control. All these functions allow users to efficiently manage the power associated with their specific peripherals, and guarantee system stability.

In summary, the ADM811SART-REEL application range and its functions make it an attractive solution for a wide range of computer and communication systems. Its ability to provide reliable operation in low-voltage and high-temperature applications, in addition to its configurable parameters make it a great solution for applications that require space and power restrictions.
