The power management IC mainly plays a role in the transformation and distribution of electric energy in the circuit equipment. Of course, it also mainly provides power for electric energy management and can output power to the subsequent circuit.

There are still many main categories of power management ICs. For example, a change in the flow of AC conversion is basically the control of circuits and switching transistors. The other is a conversion of DC to AC, which includes the change of the voltage regulator. In the face of power factor control, the automatic power output circuit is still very good, and it can play a better control role, so it will also show better results when it is used in the face of driving power. In the electronic system, the conversion and detection of this kind of electric energy is still very obvious. It can not only charge the lithium battery, but also has overcurrent and overvoltage protection, and even has the function of detecting the internal temperature. Although the size of this kind of chip on the market is decreasing, its function is very powerful, so this kind of system still has high requirements on the power supply voltage.

When choosing a power management IC, you must see what this function is like, especially the current, voltage and temperature. These conditions are still very obvious, so you should also see what kind of chip is more suitable when you use it. Different chips have different functions, some can perform power management on lithium batteries, some can charge batteries, and the function of sleep mode is very powerful. Maybe this kind of chip will not attract attention, but in fact, many electrical devices need this kind of product, including the anchor network, mobile phone computer and so on. The main function of this chip is to manage the process of charging and discharging. For example, common screen lamp beads and vibration motors inside mobile phones need this chip to manage.

In the market, we will find that whether it is a fast charging chip or a charging chip, etc., it is actually a kind of power management chip, but the name is different, just like how AC power becomes the power supply for mobile phones and the AC change required by computers. DC, etc., this is a type of power management chip.
