PMIC - Supervisors are used to provide system reset and to monitor under-voltage and over-voltage conditions in power supply designs. ADM1815-R22ARTZ-RL is a PMIC Supervisor specifically designed for embedded applications. It is primarily used to control system reset and to regulate the power supply with its low-voltage and over-voltage detection capability. The chip provides an accurate and reliable reset signal generated by its power-on detection circuitry, which helps to prevent any malfunctioning caused by unpredictable power glitches in the power supply.

The ADM1815-R22ARTZ-RL consists of a core analog block and a sequential circuit, which work together to detect power-on conditions and to generate a reset signal. The core analog block is a voltage detector, which can accurately detect low-voltage, over-voltage, and power-on conditions. It then sends a corresponding logic signal to the sequential circuit. The sequential circuit is a CMOS logic circuit, which triggers a reset signal when the voltage detector receives a power-on detection and when the reset timer times out.

The primary applications of ADM1815-R22ARTZ-RL include computer systems and embedded systems. It is especially suitable for embedded application circuit designs due to its detection precision and high integration. In a computer system, the ADM1815-R22ARTZ-RL can be used to detect under-voltage and over-voltage conditions and to provide a reset signal before any damage is caused to the system. The reset signal allows the computer system to restart and re-initialize all its parameters and regain its correct operating status.

When used in an embedded system, the ADM1815-R22ARTZ-RL can be used to detect power-on conditions and to monitor the power supply voltage. This ensures that the system functions correctly and that any malfunctioning caused by unstable power supply is avoided. The ADM1815-R22ARTZ-RL has an adjustable reset timer, which allows the user to set the time within which a reset signal must be generated. This is important in embedded applications as reset time can vary from system to system.

The ADM1815-R22ARTZ-RL has a low-voltage threshold of 1.4V, which is suitable for low power applications. It also has a reset output of 5V~19V for usage in applications with higher voltage. The PMIC also has programmable timeout, allowing users to choose the reset time. The detector consists of a low-power current source, which helps to reduce the power consumption of the device.

In summary, the ADM1815-R22ARTZ-RL is an efficient and reliable PMIC Supervisor designed for embedded and computer applications. Its low-voltage and over-voltage detection capability along with the adjustable reset timer make it ideal for these applications. Furthermore, its low power current source helps to reduce the power consumption of the device, making it energy efficient as well.
