PMIC (Power Management Integrated Circuit) supervisors have been an integral component of power and energy management since the first devices became commercial in the late 1970s. PMIC supervisors are devices that are used to monitor and control power-mounted circuits, such as power converters, AC/DC power supplies and DC/DC voltage regulators. With modern integrated circuits, PMIC supervisors provide a variety of features to ensure power reliability and cost-effectiveness while complying with industry and system standards. BD4826G-TR is the one of PMIC supervisors and it has its unique application field and working principle.

BD4826G-TR is a PMIC supervisor chip developed by ROHM Semiconductor, which provides protection and status monitoring functions for power management applications. The BD4826G-TR is primarily used in applications such as office automation, telecommunications, consumer and industrial electronics, to provide over-voltage, under-voltage, over-temperature and brown-out protection. It also provides power-on reset, power supply status monitoring and system reset functions, and can be used for product safety and reliability improvement.

BD4826G-TR is a very versatile device with a wide range of application fields. It can be used for over-voltage protection for power line equipment and systems, such as power converters, AC/DC power supply, DC/DC voltage regulators and other applications that require power quality improvement and monitoring. BD4826G-TR is also used to ensure system reliability by providing reset and power-on sequencing features. In addition, it can be used in communications systems, such as wireless base stations, optical ports, radars and remote nodes, to monitor and protect the system from over-voltage, under-voltage, over-temperature and brown-out conditions.

This BD4826G-TR PMIC supervisor operates in a very simple and straightforward way. It has an integrated comparator and a voltage reference generator. When the voltage at the control pin exceeds the reference voltage, the comparator output will make a high signal. When the voltage at the control pin falls below the reference voltage, the comparator output will make a low signal. This high or low signal can then be used to switch on or off the power line, as required. The BD4826G-TR also has two power-on sequence pins, which enable system designers to control the power-on sequence of the system.

In addition, the BD4826G-TR includes a system reset function. This function uses a timed reset output to protect the system in the event of a power failure. This output can be used to reset the system or to power up or down the system, ensuring reliability and protection. The device also has built-in protection for over-temperature and brown-out conditions, and can be used to monitor power supply voltage.

The BD4826G-TR PMIC supervisors provide a robust and cost-effective solution for power management applications. The device is designed with integrated circuit technology and user-friendly in mind, providing a simple and easy-to-understand system design and monitoring option. The device is also designed to provide high performance and compatibility with industry and system standards, ensuring power stability and reliability. It is an ideal choice for applications that require power protection and reliability.
