Power management integrated circuits (PMICs) are a form of integrated circuit that manages and regulates the power supply within electronics and device systems. PMICs perform various functions, such as converting and regulating voltages, providing protection against overloads or short circuits, and many more. They are typically used in power-sensitive applications, such as computers, mobile phones, and other portable electronics. Supervisors are one type of PMIC that provide additional functionality, such as system reset, power-on reset, and failure detection.

The BD4823FVE-TR is a PMIC supervisor by ROHM Semiconductor. It is designed to protect microprocessors, memories, and other electronic components from unexpected power drops, over-voltage and over-current conditions. The device is fully integrated into the system, allowing for quick and easy implementation. It is RoHS compliant and is rated up to 40V.

The BD4823FVE-TR has two built-in power supply detectors that provide protection for two power rails. It provides protection against over-voltage, over-current, and over-temperature conditions. The device also includes an internal watchdog timer with an adjustable time-out period. The watchdog timer helps to ensure proper system performance and reliability by resetting the system when the system fails to respond to specific conditions.

The BD4823FVE-TR also features a built-in reset interval timer. This feature helps to manage the reset interval for the system. It monitors the system to detect any unexpected behavior, such as overheating or unexpected power drops, and can generate an interrupt signal and reset the system in case of such events. The reset interval timer can be adjusted depending on the application and can be set to reset the system cycles.

The BD4823FVE-TR also includes an adjustable interrupt threshold and a window-style watchdog timer. The adjustable interrupt threshold is used to detect low-range voltage or current drop. The window-style watchdog timer helps to detect and prevent system failures caused by faults that occur outside of the window of normal operations. The window-style watchdog timer has an adjustable window size and can be used to detect and prevent system failures caused by faults outside of the window of normal operations.

The BD4823FVE-TR is well suited for applications such as motor and home automation, health monitoring, and industrial control systems. It is suitable for use in a number of different environments and can withstand high levels of vibration and temperature extremes. The device also has a wide operating temperature range, from -40°C to +125°C, which makes it ideal for use in harsh environments.

In conclusion, the BD4823FVE-TR by ROHM Semiconductor is a PMIC supervisor that offers comprehensive protection against power drops, over-voltage and over-current, and provides a reset interval timer and adjustable interrupt threshold. It is designed for use in applications such as motor and home automation, health monitoring, and industrial control systems. The device is designed to withstand high levels of vibration and temperature extremes, and can be used in a wide range of environments.
