The charging IC chip manages the charging process and charges the battery with a suitable current. Generally, it will go through three stages of trickle charging, constant current charging, and constant voltage charging. The IC in the charger detects and controls the charger. When the IC detects that the rechargeable battery is fully charged, the IC will automatically cut off t...

Because the brushless DC motor not only has a series of advantages such as simple structure, reliable operation and convenient maintenance of the AC motor, but also has the characteristics of high operating efficiency, no excitation loss and good speed regulation performance of the DC motor, so it is widely used in various fields of today‘s national economy. , such as medical ...

Ordinary power supply is generally linear power supply, linear power supply refers to the power supply in which the adjustment tube works in a linear state. In the switching power supply, it is different. The switching tube (in the switching power supply, we generally refer to the adjustment tube as the switching tube) works in two states: on and off: on - the resistance is ver...

So what is the role of chip resistors and chip capacitors in integrated circuit boards?

With the rapid growth of the semiconductor industry in recent years, some businesses in the component market are driven by their interests, and power management IC refurbishment has become an increasingly common problem. There are many goods and so on. When it comes to the authenticity of the original electronic components, it is nothing more than need to distinguish, so we nee...

In many electronic devices, there are many electrical devices that require the supplied current to be kept constant. Generally, this kind of power supply that can provide constant current to the load is called a constant current source. The so-called charging IC cross-current does not mean that the current value is absolutely unchanged, but the change is relatively small, and i...

If the power chip is hot, it means that the chip is already working abnormally. If it is hot for a long time, it is easy to burn out. The hot power chip is mainly caused by two reasons: 1. The load current is too large; 2. The heat dissipation treatment is not done well, and the power supply Engineers need to make corresponding improvements in the design from the design source,...
