ADM809SARTZ-REEL

PMIC - Supervisors are a broad category of integrated circuit (IC) used in a variety of microelectronic applications. The ADM809SARTZ-REEL is one of the many integrated circuits in this category. This essay will explore the application field and working principle of the ADM809SARTZ-REEL.

The ADM809SARTZ-REEL is an integrated circuit developed by Texas Instruments. It is a low-cost, low-power device that provides power-on reset (POR) and power-good functions. It can also detect under-voltage and over-voltage conditions, as well as brown-out and black-out conditions. It can provide a monitoring and control system that can be used to prevent under-voltage and over-voltage conditions.

The primary application field of the ADM809SARTZ-REEL is in microcontroller applications, such as microcontroller-based systems. It is typically used to monitor and control the system’s power supply to prevent faulty operation, and to shut down the system in unsafe operating conditions. It can also be used to monitor the operation of the system and to reset it after a fault has occurred. In addition, the POR and power-good signals from the ADM809SARTZ-REEL can also be used for communications between microcontrollers in a multi-processor system.

The working principle of the ADM809SARTZ-REEL is based on its three power rails: the power supply (VCC or VDD), the ground (GND), and the system reset (RESET) rails. The device is connected between the VCC and GND rails, and it monitors the voltage on each of the two rails. If the voltage on one of the two rails drops below the device’s low-voltage threshold, then the device will assert the system reset signal on the RESET rail. This will cause the system to reset and restart. If the voltage on one of the two rails rises above the high-voltage threshold, then the device will de-assert the RESET signal and allow the system to continue operating.

The ADM809SARTZ-REEL is also designed to monitor and control the voltage on either the VCC or GND rail. It can detect under-voltage or over-voltage conditions, as well as brown-out or black-out conditions. If either of these conditions is detected, then the device will assert the RESET signal and shut down the system.

In summary, the ADM809SARTZ-REEL is an integrated circuit designed to provide POR and power-good functions, as well as the ability to detect under-voltage and over-voltage conditions. It is primarily used in microcontroller-based systems, and it works by monitoring and controlling the voltage on the two power rails and asserting the system reset signal when it detects an unsafe voltage condition. The ADM809SARTZ-REEL is a cost-effective and reliable solution for power supply monitoring and control, and it can provide precise monitoring and control of microcontroller-based systems.
