Induction cooker OB2226AP power chip, DIP8pin, in Supor, Jiuyang (such as JYCP-21ZD-A) induction cooker has applications. OB2226SP can be used instead, but the seventh and eighth legs should be connected.
Pin function: OB2226SP adopts DIP7 pin package.
FSBO16 pin voltage value is usually 5V, but depends on the design of induction cooker. If you need more specific information, please refer to the FSBO16 data book. Regarding alternative chips, in general, you can try to replace FSBO16 with chips of the same type. For example, you might consider using chips such as FSB02FSB030 instead. However, this requires you to have the relevant circuit designAnd debugging capabilities to ensure the compatibility of the replacement chip with the original device.
④, measure the voltage regulator circuit components of the 15 V voltage, such as: the three-terminal voltage regulator chip to the LM7805, and the components around the chip.
Induction cooker voltage is too low or too high protection, sampling part in 220V AC part, the circuit is relatively simple, there are two rectifier diodes, several voltage resistance and capacitor composition, give you a pattern to see, the red box inside the component is overvoltage protection sampling circuit.
The display above the induction cooker is poor: when we use the induction cooker, sometimesThe display above the induction stove is not bad, or it is not displayed, in this case, we should check the CPU and the light board LED.
Supor induction cooker Supor can be said to be the largest research and development manufacturer of cookware, its induction cooker production relies on its own unique production technology and processing technology, occupies an important position in the induction cooker industry, market share often with the United States for the first. Supor induction cooker models are also very rich, and the price is concentrated between 179 yuan - 599 yuan, and the cost performance is also very high.
Front-end Bus (FSB) Frequency Front-end bus (FSVCC is the positive terminal of the power supply, GND is the power supply ground. Data storage: In the 16-pin single-chip microcomputer chip RS pin function is to store data, RS for register selection, high level 1 to select the data register, low level 0 to select the instruction register.
Functions are as follows: In the STC8H1K16 MCU, P40 and P41 pins can be used as I2C bus communication to achieve data transmission between devices. The P0 and P1 pins serve as the timer inputs.
If the JTAG interface is enabled, pins PC5 (TDI), PC appear even if resetPull-up resistors of 3 (TMS) and PC2 (TCK) are activated. Port C can also be used for different special functions. Port D (PD.PD0) Port D is an 8-bit bidirectional I/O port with a programmable internal pull-up resistor. The output buffer has symmetrical driving characteristics, which can output and absorb large current.
The LS160IC package consists of 16 pins and contains a 4-bit synchronous counter circuit that allows mod wiring for ten years of counting without an external logic chip. This can be achieved by wiring multiple 74LS160s together (cascading)The function is that when the forbidden end is zero, the CMOS three-group two-way analog switch CD4053BE works, otherwise the CMOS three-group two-way analog switch CD4053BE is disabled.
