BU4848G-TR

Power management integrated circuits (PMICs) are semiconductor devices that rapidly and effectively manage multiple types of power in the most efficient manner. Although PMICs are mainly used in battery-powered systems, they can also be used in other applications such as those powered by AC or DC sources, or USB connection. PMICs are a key component used in many complex applications and are used in a wide variety of application fields, such as automotive, industrial, consumer electronic, and computer systems.

PMICs consist of several functions including voltage regulation, load balancing, battery charging, current monitoring, and system monitoring. One type of PMIC, Supervisors, are specialized integrated circuits designed to monitor power and system operation. Supervisors are an important part of any system and are useful for monitoring the status of various power systems and managing power conditions. They can detect faults and act accordingly, switching off loads and providing early warnings of system problems.

The BU4848G-TR is a power supervisor with a single-channel output and several built-in functions. It is designed to monitor and control multiple power sources, such as paralleled DC/DC converters, adaptive bus voltage and single channel output system. The device provides overcurrent protection and monitors common power-on reset (POR) and power-down reset (PDnRES) conditions. Additionally, it offers 1MHz frequency support with a fast response and high precision.

The BU4848G-TR is mainly used for monitoring and controlling multiple power sources, especially for applications that require multiple power sources. It is capable of detecting a wide range of fault conditions, such as overcurrent and overtemperature, and can switch off the power source and provide warning signals. This makes it a suitable choice for many applications such as automotive, medical and industrial systems, as well as portable, consumer and computer products.

The working principle of the BU4848G-TR is based on the integrated protection circuit. When an input voltage is detected, the voltage comparator in the device performs a comparison between the input voltage and the reference level. If the input voltage exceeds the reference level, the device will trigger the POR or PDnRES control signal, depending on the situation. Additionally, the device can detect overcurrent and over-temperature conditions, and it can switch off the power source and provide warning signals.

The BU4848G-TR can provide protection for power supplies and systems that require accurate voltage and current monitoring. It can detect a variety of fault conditions, such as overcurrent and overtemperature, and can switch off the power source and provide early warnings of system problems. This makes it a good choice for use in automotive, medical and industrial systems, as well as portable, consumer and computer products.
