Power management IC (PMIC) is a type of integrated circuit (IC) dedicated to power management. It simplifies the efficient management of power on systems, washing machines, and other kinds of electronics. One of the most important PMICs is the BU4846G-TR, which is an integrated circuit (IC) supervisor circuit. The BU4846G-TR is commonly used in applications such as industrial equipment and robotics. This article will discuss the application field and working principle of the BU4846G-TR.

Application Field

The BU4846G-TR is a low-voltage/low-power integrated circuit supervisor circuit. This means that it is ideal for applications with a power supply in the range of 1.6V to 5.5V. It is designed specifically for monitoring automatic reset and power-fail conditions for systems requiring tight power control. It is particularly used in the industrial and automotive sectors, and is often applied to tasks such as robotics and control systems in industrial settings.

The BU4846G-TR is a robust IC supervisor circuit, providing reliable power control and monitoring for such applications as cooling fans, vehicle equipment and industrial/household machinery. It is designed to provide quality and stability, making it an ideal choice for applications that require power control and monitoring.

Working Principle

The BU4846G-TR is based around a voltage monitor circuit. This circuit serves to monitor the power supply voltage and then take appropriate action if it falls below a certain level. This is achieved by setting the reset/power-fail threshold to between 1.6V and 5.5V via an external resistor. When the supply voltage drops below the threshold voltage, an automatic reset will be initiated. This reset ensures that the system remains within the safe range and that power is not lost.

The BU4846G-TR also features a watchdog timer circuit. This circuit monitors the system for any fault conditions that may occur. If the timer reaches a certain count, the system will be reset. This timer can be adjusted from 1.5 sec to 4.9 sec, depending on the application’s needs.

The BU4846G-TR also features power-on reset, which is designed to keep the system stable and in good working order even when the power supply is switched on and off. This reset is active after the power supply voltage is restored and hence the system can be kept stable even if the power supply is interrupted.

Finally, the BU4846G-TR includes a temperature-sensitive circuit, which protects the system from high temperatures. This circuit ensures that the temperature of the system remains within the safe operating temperature range. The temperature can be adjusted by connecting an external resistor.

Conclusion

The BU4846G-TR is an integrated circuit supervisor circuit suitable for applications where tight power control and monitoring is required. It is particularly applicable in the industrial, automotive and robotics sectors. The BU4846G-TR provides excellent protection from power-fail disruptions, with automatic reset and watchdog timer functions, and temperature-sensitive protection. This makes it an ideal choice for any system where tight power control is needed.
