2, PIC12F675 type corePieces. According to the query, the PIC12F675 chip is an 8-pin package and 8-pin ground, which is the commonly used power supply model in the electric vehicle charger, so the eight-pin chip is a pin connected to the power supply and the eight-pin ground is the chip of the PIC12F675 model.
3, this octagonal integrated block is used for regulating voltage sampling current and so on.
4, PIC12F675. Electric car is a common scooter, and after the electric car charger post-op amp chip, the 8-pin package and 8-pin ground is the PIC12F675 model, which is a very commonly used power supply type in the electric car chargernumber A chip is a small piece of silicon that contains integrated circuits and is part of a cell phone, computer or other electronic device.
5, in the common 8-pin power chip, the fourth and sixth pins are GND models, including linear regulators such as LM780LM7806, and some switching power chips such as LM257LM2576. You need to further confirm the appropriate model according to the specific application and specifications.

Pin power chip TB6806 is a high performance primary side controller that provides high precision constant voltage and constant current output performance, especially suitable for low power offline charger applications. At the same time, TB6806 also supports quasi-resonant step-down LEDFor constant current and constant voltage output applications, just short connect SEL pin to GND pin.
HT46R01C MCU for 1 pin VCC, 8 pin GND, the rest can be set to IO, you can use the external crystal oscillator. PIC12f675 MCU for 1 pin VCC, 8 pin GND, the rest can be set to IO, you can use the external crystal oscillator. STC15F104E MCU is 2-pin VCC, 4-pin GND, and the rest can be set to IO, and external crystal oscillator is not available.

This octagonal integrated block is used for regulating voltage sampling current and many other purposes.
The switching power driver chip is generally not directly connected to the transformer. Generally, one of the pins outputs a PWM signal to that MOSFET. And the average engineer wouldn't do that with the pinsGuide this chip exactly what, there is no reverse operation.
is estimated to be a single chip computer, even if you know the model can not do it, bought a new, can not work without a program. If it is not a single chip computer, it is difficult to guess the model, can you find the manufacturer to repair it?
Generally more feet, then the analysis is a 4-bit IIC bus IO expander. But I haven't seen the 4BITIO extender either, just take it for granted. The general IO expander is 8BIT 16BIT, then the 5 pin is an ordinary IO port, which makes sense.Chip 8-pin integrated model
1, PN8680. The octagon chip has LM35PN8680, NE555 and other models, and the octagon chip on the power board of Kehai Everywhere is PN8680. Octagonal chip, also known as octagonal integrated circuit chip, is a form of integrated circuit chip.
2, you can look at TOP23X series single chip power supply IC. It's very similar to the way you talked about the IC application. For example, TOP220 1 pin start resistor, 8 grounding, 6 pin none, 5 pin switch transformer, 4 pin control end. This IC is found in MOTOROLA chargersIt's common. You can buy an old charger and take it down.
3, THX202H instead. According to the network data query, the 8-pin integrated block 202 is replaced by THX202H, the first is the switching power supply integrated circuit that adopts patented technology to prevent overload and saturation and can meet higher green environmental protection standards.
