Power management integrated circuits, or PMICs, are typically used in electronic systems that require power optimization and management. The BD4737G-TR PMIC falls into the supervisors category, which are typically used to monitor and protect low power designs. This PMIC provides basic power supervision functions such as circuit protection, reset and watchdog timer in order to minimize user design costs and effort. In this article, we will discuss the application field and working principle of the BD4737G-TR.

Application Field of the BD4737G-TR

The BD4737G-TR is designed for application in consumer electronics and computer, telecom and automotive systems, where power optimization and management are critical. The BD4737G-TR offers a range of features to ensure the reliable operation of power systems with low power consumption, including over-temperature protection, under voltage lockout, over voltage protection and brownout protection.

The BD4737G-TR also has an adjustable reset output timer, allowing the user to customize the reset signal to suit the specific requirements of their application. The wide range of adjustable reset output timing includes a 1s to 32s watchdog timer and a 2ms to 1s manual reset timer. This wide range of adjustments allows the user to tailor the BD4737G-TR to the individual requirements of their application.

Working Principle of the BD4737G-TR

The BD4737G-TR works by monitoring the input voltage of a power system. When the input voltage is outside of the safe range as set by the user, the BD4737G-TR will generate a reset signal to the power system. The reset signal will then cause the power system to enter a safe state, preventing any damage from occurring.

The BD4737G-TR also features a watchdog timer that monitors the system for any malfunctions. If no reset signal is received within the set time frame, the watchdog timer will reset the system. This allows the system to continue to operate without interruption and without user intervention.

In addition to reset and watchdog timer functions, the BD4737G-TR also offers over-temperature protection, under voltage lockout, over voltage protection and brownout protection. This helps to prevent power system malfunctions or damage caused by unexpected fluctuations in input voltage.

Conclusion

The BD4737G-TR PMIC is an excellent supervisor for low power designs. It offers a wide range of features to ensure the reliable operation of power systems with low power consumption. It offers protection against over-temperature, under voltage lockout, over voltage protection and brownout protection. Additionally, the adjustable reset output timer and watchdog timer provide the necessary features for a robust power management system. By using the BD4737G-TR, users can be sure their designs will be protected and optimized for reliable operation in a variety of applications.
