PMIC (Power Management Integrated Circuit) supervisors are essential in an increasingly power-sensitive and power-dependent electronics industry. Such devices provide more accurate and reliable protection against overcurrent, overvoltage and other damage to the device it is connected to.One such device is the BD5248FVE-TR, an overvoltage and overcurrent supervisor from Rohm Semiconductor. It provides reliable and accurate protection against overvoltage and overcurrent and is thus ideal for a variety of electronic applications such as notebook computers, LCD TVs and other consumer electronics.The BD5248FVE-TR consists of a control circuit, reference voltage, comparator and detection circuit. It also has a PWM output which can be used to control system power down or reset.The control circuit is responsible for monitoring the system’s regulated voltage and output current. It compares these values against the factory-set thresholds in order to detect any out of range readings. If an out of range reading is detected, the control circuit will generate a signal to reset the system. The control circuit is also responsible for controlling the reference voltage, which can be tailored to the particular application.The reference voltage is generated by the internal oscillator and can be adjusted to suit the system’s frequency requirements. It should be set to ensure that the system is not subjected to any potential damage due to a voltage spike or drop. The reference voltage is then compared to the control voltage to detect any voltage mismatch.The comparator and detection circuit are responsible for detecting any overcurrent or overvoltage conditions and generating a warning signal if one of these conditions is detected. The key feature of this circuit is its low detection voltage and low voltage drop which helps to ensure reliable operation. The circuit also has an adjustable open collector output which can be used to control system power down or reset.The BD5248FVE-TR is available in various packages and is ideal for use in automotive, industrial and consumer applications. It is an economical choice for applications requiring an advanced, reliable and accurate overvoltage and overcurrent detection and protection system.In conclusion, the BD5248FVE-TR is an excellent choice for protection against overvoltage and overcurrent in a wide range of applications. Thanks to its control circuit, reference voltage, comparator and detection circuit, it can provide reliable, accurate protection against potential damage due to a voltage spike or drop. In addition, the adjustable open collector output can be used to control system power down or reset. This makes it an ideal choice for a range of applications requiring reliable protection against overvoltage and overcurrent conditions.
