1, lamp charger 14 pin chip is C043 domestic label. According to the query of relevant materials, it is publicly displayed that the chip of the 14 pins of the 6-lamp charger is C043, which is a domestic label and a double D trigger. C043 and CD4013 have exactly the same logical structure and function, but both pinsThe arrangement is different.
2, electric car charger turn light control chip model 3842,3843,3844,3845. The electric vehicle charger is a charging device specially configured for the electric bicycle battery. Classification of chargers: with and without power frequency (50 Hz) transformers, can be divided into two categories.
3, is an 8-bit micro-control chip (MCU), the function is the same as KAPC4L13SP130H1, PIC12F675. Used to control the charging process (doubles as a control indicator).
4, uc3842 LM324 chip. The special chip for electric vehicle charger is a chip designed for the application of electric vehicle charger, which can accurately control and manage the charger, improve the charging efficiency, and ensure the safety and stability of the charging process, all of which are uc3842 LM324 chips.
5, the integrated circuit IC1 used by the charger you see is 3842 chip, which is a commonly used switching power supply chip, and the switching power circuit composed of it can make 220V AC input into low voltage and high frequency AC, and then after rectification into direct current, you can charge the battery.
1, if it is the same price as 13001 or 13002, it must choose 13003, it is relative to the latter two, large power. In the case of no increase in circuit power, it can also be used without heat dissipation measures. Generally, the mobile phone charger is 600mA current, 13001 is OK, and 13003 is some waste.
2, the charger of the mobile phone can be mixed, the manufacturer is in thisThe above point will also be taken into account, because it is a USB interface, even if it is not intentional, it is easy to mix. Although the standard interface of the mobile phone charger is USB, it may not reach the original charging speed or current of the mobile phone when it is mixed.
3, this is because the emergence of iPhone expansion, so that some old models of Apple mobile phone users only spend a small cost to get more storage space, so this part of the users are not willing to change the phone, affecting Apple's profits. So Apple from the iPhone 8, strengthen the processor, motherboard, flash memory "three in one."Encryption.
Different process. The original chip of Apple charger is different from the original process. The original contained one of Apple's identification chips; The common charger on the market is a cheap domestic chip, but it can be compatible with Apple. Some manufacturers save costs. Refuelling is different. It's super high imitation at best. In short, high quality thread.
Original parts usually have a higher price, but also can provide more reliable and stable performance. And the original parts refer toAccessories made by other manufacturers that meet the specifications of the iPhone, but are not directly produced or licensed by Apple.
The data line with the chip contains the function of data encoding and decoding in the chip, and there is no more, and the 5V2A charger chip U6315, which is generally charged by constant current and constant voltage, and automatically turns to trickle charging after the battery is full.
The original charger of the iPhone phone is a good manufacturer, the voltage and current of the charger are relatively stable, so the mobile phone is relatively stable, rather than the electricity of the original chargerVoltage and current cannot guarantee stability, charging is easy to cause damage to the battery, and the phone is super slow to charge when playing games using non-original chargers.
Different current: the current of the original charging of the Apple phone charger is constant voltage and constant current, which will not cause harm to the phone. Apple mobile phone charger is not original may cause the battery to overcharge and overvoltage, and the battery is easy to age. The quality is different: the original Apple phone charger is a qualified product, and it is not easy to have quality problems.
Withstand pressure600V working current 6A unidirectional thyristor, unidirectional thyristor. Used for overvoltage protection and overcurrent protection. The long foot is the trigger pole, the middle foot is the anode, and the short foot at the end is the cathode.
The commonly used integrated circuit of the electric car charger is 555, and the TL494 is also more commonly used. Microcontroller is actually a microcomputer.
is generally between 10-30V. 7 is the power pin, and 20v is normal. In general, directly change a 3842, ensure that the mos does not break down, disconnect the gate, power, multimeter test 3842 6 pin pendulumMoving voltage is basically OK.
PF7001S. The electric car charger 14 pin chip is C043 domestic label, is double D trigger, model PF7001S. Power management chip (PowerManagemenTIntegratedCircuits), is in the electronic equipment system for transformation and distribution of electrical energy, detection and other power management responsibilities of the chip.
uc3842 LM324 chip. The special chip for electric vehicle charger is a chip designed for the application of electric vehicle chargerIt is enough to accurately control and manage the charger, improve the charging efficiency, and ensure the safety and stability of the charging process, all of which are uc3842 LM324 chips.
IP5407. Battery management SOC chip, integrated DCP function, model IP5407, is a lithium battery charging chip. Power bank, a portable charger that can directly charge a mobile device and has its own storage unit.
If the charging ic is just onRoad damage, generally just can not charge, no current past.
Charging ic bad can also charge, charging ic is an essential part of the charging equipment, charger chip as the core components of the charger, mainly converts alternating current into matching direct current to "transmit energy", in the charging link has played a vital role, directly affecting the efficiency and life of the charger.
According to the query Zhongguancun online that the charging ic is broken, it can not be charged or the charging speed is slow, and the charging flash backward situation. A broken charging ic will cause the phone to connect to the computer USB cable can not be
