PMIC – Supervisors always play an important role in a wide range of applications. In this case, we are discussing an essential component, the BU4924FVE-TR Supervisor from ROHM Semiconductor. Specifically, we will be focusing on the application field and working principle.
BU4924FVE-TR: Application Field
The BU4924FVE-TR supervisors are designed to be used in various applications, including cell phones, PDAs, digital still cameras, portable audio/video players, and so on other convergent applications. It offers an extremely simple solution for supervisor circuits by integrating a reset generator, power-on reset generator, voltage detector, clock generator, input logic circuit, watchdog timer and delay circuit on a single chip device.Added to the above mentioned features, the BU4924FVE-TR can be employed in a range of applications such as handhelds, sensors, motor control, displays. In these type of systems it is possible to use it to detect the voltage level of the supply, to monitor the microcontroller\'s operation, to generate a reset signal, reset timing control, system clock, and/or watchdog pulse to protect against crash of the system.
BU4924FVE-TR: Working Principle
The BU4924FVE-TR supervisor is an integrated circuit (IC) consisting of a Reset Generator, Power-on Reset Generator, Voltage Detector, Clock Generator, Input Logic Circuit and Watchdog Timer/Delay Circuit.The most important part of the supervisor IC is the reset generator. It generates a reset signal by sensing the voltage level and the changes in it.When the voltage drops below the threshold, the reset generator is triggered and correctly regulates the reset signal. The power-on reset generator and threshold voltage detector help ensure that the reset output initiates at the correct voltage.The other features, such as clock generator and watchdog timer, are all there to protect the system from crashing due to unexpected events and unforeseen issues.The clock generator can generate clock pulses, while the watchdog timer monitors the system’s operation to issue a reset signal if necessary. This ensures that the system remains running as intended.Finally, the BU4924FVE-TR’s integrated delays can be set to toggle the system’s reset when needed, thus allowing the system to continue running without interruption.
In conclusion, the BU4924FVE-TR supervisor is the ideal IC for robust performance in a variety of applications. Its reset generator, power-on reset generator and voltage detector all help ensure that the system remains running safely and free from unexpected errors. Additionally, the built-in clock generator and watchdog timer can protect against unforeseen issues, while the integrated delays ensure that the system never experiences a reset surprise.
