Power management integrated circuit (PMIC) refers to the integrated circuit (IC) that provides necessary voltage and current to the proper running and functioning of an electronic device. It consists of several elements such as voltage regulators, power factors, clocks, phase lock loop (PLL) and current limiting. PMIC is extensively used in embedded systems to manage different loads, switching and distribution of power. These chips offer superior flexibility, protection and performance.

On the other hand, PMICs are also used in various kind of applications such as smart phones, automotive electronics, industrial systems, etc. In this article, we will discuss one such integrated circuit, the FDG6323L. This PMIC belongs to the classification of Power Distribution Switches, Load Drivers and it performs a variety of tasks.

Application Field:

FDG6323L is a highly integrated Audio Power Management IC designed for Class D audio amplifiers. This PMIC can integrate drivers for up to eight audio power switches, with embedded feedback resistor, as well as an integrated voltage detector (VD). The FDG6323L has flexibility for programmable current protections and easily controlling the output power transistors. It is designed for up to 24V rail, capable for making a cost-effective and robust solution for Class D applications.

It can also be used in computing applications such as the LVDS display interfaces, system power supplies and CPU power rails. This PMIC is highly capable for regulating, distributing and controlling power in different kinds of load. Besides that, it can be used to control the communication interface between power modules, modules with different clock domains, and also as a protection circuit to prevent over-voltage, over-current and over-temperature incidents.

And, the FDG6323L is implemented in the smart home applications like doorbell, intelligent cameras, and home security systems. It is capable of regulating, controlling and protecting many kinds of load, making it highly suitable for such kind of applications.

Working Principle:

The FDG6323L is mainly used to monitor and manage the amount of power being drawn from a device. It works in a simple but effective way. When the device is turned on, this PMIC will first detect the voltage level at the input port and adjust the output port accordingly. If the voltage level is lower than the recommended voltage level, the FDG6323L will automatically increase the output voltage. On the other hand, if the voltage level is higher than the recommended voltage level, the FDG6323L will reduce the output voltage.

Also, the device can monitor the current level of the output port, and it can limit the current to the device in order to prevent any power related damage. Once the current level has exceeded the recommended level for a certain period of time, the PMIC can trip the fuse and shut down the power supply. This function is designed to protect both the device and the user from any potential over-voltage, over-current and over-temperature incidents.

Furthermore, the FDG6323L also have protection functions for short circuit, anti-surge and electrostatic discharge. This PMIC has an adjustable output duration, which allows the user to adjust how long the output is active. This feature can be used to conserve energy in applications such as smart home devices. Additionally, the device also supports an innovative fail-safe mode that can automatically detect and reset any output overload.

In conclusion, the FDG6323L is a high performance PMIC that provides superior flexibility, protection and performance. It is capable of regulating, controlling and protecting many kinds of load. It integrates drivers for up to eight audio power switches and is used in many applications including LVDS display interfaces, smart home devices, and home security systems. Overall, the FDG6323L is an excellent choice of PMIC for power distribution switches, load drivers and other power related applications.
