Introduction

PMIC (Power Management Integrated Circuit) is an integrated circuit that manages the power distribution and consumption in a circuit. A Supervisory PMIC is used to detect malfunctions, prevent overvoltage and undervoltage, and to provide voltage and current regulation. The ADM809TART-REEL is one of the most widely used PMIC Supervisors in the industry today. This article will discuss the application field and working principle of the ADM809TART-REEL.

Application Field of ADM809TART-REEL

The ADM809TART-REEL is a reliable and cost-effective solution for power management applications involving multiple supply rails, automatic system reset and power-fail detection. This PMIC can be used in a variety of applications, including telecommunications, industrial, automotive and consumer electronics. The ADM809TART-REEL is designed to provide efficient power and performance to comply with the most demanding power accuracy requirements.The ADM809TART-REEL has wide operating temperature range of -40°C to +105°C and is housed in Small Outline Package (SOP). This PMIC is ideal for high-performance, mixed-voltage systems due to its low-power consumption and active power management features. The ADM809TART-REEL is designed to monitor all voltage levels, such as output voltages, low-voltage ripple, overvoltage and undervoltage. It is also designed to protect against current overloads, brownouts, power shut down, power-on reset, and watchdog timer reset. The ADM809TART-REEL also includes an integrated temperature sensor that can be used to monitor temperature levels.

Working principle of ADM809TART-REEL

The ADM809TART-REEL is a low-power, low-cost, and easily expandable solution for power management applications. The device consists of a power-on reset circuit, a compare circuit, a voltage detect circuit, a watchdog timer circuit and a temperature alarm circuit. When the supply voltage rises above or falls below the preset upper and lower limit, the compare circuit detects the out of limit voltage and triggers a reset pulse. The reset pulse is sent to the power-on reset circuit which generates a reset signal and initiates the system reset.The voltage detect circuit continuously monitors the supply voltage, and can adjust the reference voltage automatically to provide better accuracy. The watchdog timer circuit provides periodic reset signals to reset the system when an external clock source is used. The temperature alarm circuit continuously monitors the system temperature and generates an alarm signal when the temperature exceeds the preset upper limit. This circuit can also detect and report the fault condition caused by overheating or aging of electronic components.

Conclusion

The ADM809TART-REEL is a reliable and cost-effective solution for power management applications. It is designed for wide range of operating temperatures and is ideal for high-performance, mixed-voltage systems due to its low-power consumption and active power management features. The device includes power-on reset, compare, voltage detect, watchdog timer, and temperature alarm circuits, making it a versatile and robust power management solution.
