The BD4942FVE-TR is an advanced, voltage-supervisor device that is designed and manufactured by ROHM Semiconductor. This product is designed for a wide variety of applications due to its wide operating voltage range and flexible features. This device monitors voltage levels and other conditions to ensure the safe operating conditions of various types of electric and electronic devices, such as microprocessors and embedded systems.The BD4942FVE-TR has a wide range of features and functions that make it a top choice for many applications. These features include: low current consumption, wide operating voltage range, adjustable reset frequency, multiple output voltage selections, adjustable voltage thresholds, and selectable active-low or active-high reset. It also includes a power saving mode that reduces power consumption at light load conditions.This device belongs to the category of PMIC (Power Management Integrated Circuit) Supervisors. PMIC Supervisors are used to regulate the power supply of electric and electronic devices by monitoring voltage levels and other conditions. When the monitored voltage levels and/or other conditions exceed the thresholds, the PMIC supervisor device will issue an alarm or shut off the power supply for safety reasons.The working principle of the BD4942FVE-TR is based on its integrated circuit that uses the latest in low-power technology and features. This chip consists of several different blocks which include: a voltage detector, a reset controller, a voltage selector, a frequency selector, and a control register.The voltage detector will detect the voltage of the power supply, and compare it with the configured voltage thresholds. When the voltage of the power supply is lower than the configured reference voltage, the chip will detect this and will generate a reset signal. The reset controller then sends this reset signal to the control register and it will force the reset output of the chip to reset the system.Moreover, the voltage selector block is used to select the appropriate voltage in order to regulate the power supply. The frequency selector is used to adjust the reset frequency, and it can be set to either low, medium, or high depending on the application. Finally, the control register allows the user to select the reset active polarity, or whether the chip will reset when the voltage is low or high.The BD4942FVE-TR is an ideal device for power regulation applications due to its low current consumption, wide operating voltage range, adjustable reset frequency, multiple output voltage selections, adjustable voltage thresholds, and selectable active-low or active-high reset functions. It is an efficient tool to ensure safe operating conditions for a wide variety of electric and electronic devices.
