PMIC - Supervisors

PMIC or Power Management Integrated Circuits are integrated circuits with the capability of combining multiple power supply and orientation-related functions into one single chip. These are used in a variety of applications, and the BU4916G-TR is one such IC used in various applications. This article will discuss the various application fields of the ICs and its working principle.

BU4916G-TR Application Fields

The BU4916G-TR is a Power Distribution and Power Supply Supervisory IC designed for power supply design in equipment for audio and visual appliances, office automation and communication. This IC is an integrated circuit composed of a voltage detector, voltage selector, and a power distribution circuit, integrated into a single chip. It has been designed to reduce the number of components and reduce the cost of parts.

The BU4916G-TR consists of two voltage detectors, one voltage selector, and a power distribution circuit, all integrated into a single chip. It has been designed for applications where a switch mode power supply is being used, and is ideal for applications where relay switching is difficult. It is used in power supply design to detect the output voltage level, and to switch the output voltage automatically between two different levels. The IC also helps to reduce the power consumption of the power supply design.

The BU4916G-TR is also used in various home appliances, such as televisions, stereo receivers, and other audio/video equipment, power meters, and various other products. This IC has also been used in automotive applications, such as in on-board computers and accessories and lighting systems. It is also used in various industrial applications, such as in motor and motor control systems, generator systems, and solar power systems.

BU4916G-TR Working Principle

The BU4916G-TR is an integrated circuit that combines multiple voltage detection and power supply functions into a single chip. It has two voltage detectors, one voltage selector, and a power distribution circuit, all integrated into a single IC. The voltage selector is used to detect and switch between two different voltage levels. The voltage detector detects the voltage level of the input voltage and switches the output voltage to the signal that best suits the needs of the application. The power distribution circuit distributes the power to the various components of the power supply.

When the input voltage, measured by the voltage selector, is greater than or equal to the preset voltage level, the IC will switch the output voltage to the higher voltage level. When the input voltage is below the preset voltage level, the IC will switch the output voltage to the lower voltage level. This switching will help to reduce the overall power consumption of the power supply design.

The BU4916G-TR uses a special operation cycle to ensure safety when switching between the two voltages. This includes a Check cycle (CM) and an Auto Switched cycle (AS). The CM cycle is used to detect if the input voltage is greater than or equal to the preset voltage level. If the input voltage is below the preset level, then the AS cycle will be initiated and the output voltage will be switched to the lower voltage level.

The BU4916G-TR is designed for high reliability and can be used in a variety of applications. It is very reliable as it features high level of immunity from noise, as well as from ESD and surge breakdown. The IC has also been designed to have low power consumption, with a power-on reset function reducing the overall power requirements of the power supply design.
