Note: The amount of use and speed of the charging IC depends on the received PWM frequency.
Charging IC is one of the most important parts in an electronic circuit (charging - feeding). This part plays a role in the voltage supply and transmission process, and its failure will lead to serious damage in the circuit. Charging IC is an extremely delicate, vulnerable and sensitive part that is highly vulnerable to damage and failure due to its connection with electric current. On the other hand, the performance of this part is such that if a problem occurs, it will involve other parts of the device as well. If this IC is damaged or a cold solder condition is created in its bases, each of the mentioned parts will suffer and problems will arise in the overall circuit performance.
When the device charges late or does not charge at all, the problem may be with the charging circuit or charging IC.
Use cases (ic charge) in electronic circuits
This IC is complementary to the feeding IC. Most of the reason for the failure of this ic is the continuous and excessive operation in all devices with functional user interfaces, for example: power bank; Mobile ; Laptops and all devices that need charging. The type of this IC is ball base or BGA.
