Power management integrated circuits (PMICs) are a type of integrated circuit designed to manage power which provide the necessary signals to control power distribution, and regulate, monitor and manage devices’s power usage. PMICs are utilized in a variety of products such as mobile phones, tablets, automotive applications, and industrial devices. One of the PMICs is L9338D,which belong to the category of power distribution switches, load drivers, and it is widely applied in electronics. In this article, its applications and working principles will be discussed in detail.

Applications of L9338D

L9338D is a good partner for electronic products and become indispensable in electronic products. It mainly used in two kinds of applications, the first is loading systems, the second is electro-mechanical system.

1.Loading Systems

L9338D is suitable for loading system while working, this chip is applied in the loading control systems. The motor and other electric equipment are connected in the loading systems. This chip can precisely control the output current as well as the speed of motor, and it can also provide protection for itself when the motor stops. This chip can bring high efficiency and safety for the loading systems.

2. Electro-mechanical Systems

The second application of L9338D is the electro-mechanical systems. Electro-mechanical systems are complex combining the work of electricity and machines and it is now widely used in many industries. As a load drive chip, L9338D can accurately controlling and monitoring the operation of these systems and ensure that they are working in a steady state. It also capable of providing accurate and fast current or voltage adjusting function in these systems. Therefore, L9338D has become an indispensable chip in electro-mechanical systems and provides great convenience for its users.

Working Principle of L9338D

The working principle of L9338D is relatively simple, the main function is to convert the low voltage to the higher output voltage of the chip, the input voltage can be 3.3V, 5V, 12V, 24V etc. and the output voltage range is from 8V to 140V.

Step 1: Monitoring

First of all, the chip will monitor the temperature and voltage of the load. Through monitoring, L9338D can automatically select the appropriate power to support the system and provide the best protection when the system is running.

Step 2: Adjusting

When the voltage or temperature of the load is not in the ideal range, L9338D will adjust the output current and voltage to maintain the acceptable level, ensuring the reliability and stability of the system.

Step 3: Protection

Another important function of this chip is providing protection. If there is something wrong in the system, the system can provide protection for the load and the chip itself. It can protect for both over voltage and over current caused by various reasons.

Conclusion

In conclusion, L9338D is a very powerful chip and it is mainly used in two kind of applications, loading systems and electro-mechanical systems. The working principle of this chip is very simple which is to monitor, adjust and provide protection. So, if you need to control a load accurately, then L9338D chip is your best choice.
