What are the functions of IP2326 charge management chip? The IP2326 has input voltage limiting function, which can intelligently adjust the charging current and adapt the adapter load. The IP2326 supports external pins to select whether to set up 2-string or 3-string lithium battery charging.
The main function is: when the battery voltage rises to 4V, DW01 will think that the battery voltage is in the state of overcharge voltage, and immediately disconnect the output voltage of the third pin, so that the voltage of the third pin becomes 0V, and the switch has no voltage due to the fourth pin.
Battery protection: Charging ics also undertake the important task of protecting batteries. It can monitor the battery power and temperature, when the battery power is too low or the temperature is abnormal, the charging IC will automatically stop charging to avoid overcharging or overheating of the battery, and protect the life and safety of the battery. In addition to the basic charge management functions, the charging IC of modern mobile phones also has some advanced features, such as fast charging, wireless charging, reverse wireless charging and so on.
The charging chip is to manage the charging process, including the charging IC and undervoltageDetection IC, temperature detection IC, over current and over voltage detection IC, etc. IC charger is a charger with IC protection function, with a microcomputer integrated into a block, is a small circuit plate charger. Specifically, it is possible to monitor the working state of the charger at any time through the IC (that is, the chip) to provide the best charging method and the least damage to the battery, the core of which is the IC.
Power management chip, also known as power supply ic, also known as pulse width modulation chip (pwm), the motherboard is called: programmable pulse width modulation chip, mainly responsible for controlling the main power supply of the cpu, generally located near the cpu socket, you can see24 chips.
2, electric vehicle charger lC is the meaning of integrated circuit, the number behind is the number of integrated circuit, ICIC2,...... Let's wait. The integrated circuit IC1 used by the charger you see is 3842 chip, which is a commonly used switching power supply chip. The switching power supply circuit composed of it can make 220V AC input become low-voltage and high-frequency AC, and then become direct current after rectification, you can charge the battery. < / p > < p > 3, power management chip (PowerManagemenTIntegratedCircuits), is inA chip in an electronic device system that performs the conversion, distribution, detection, and other functions of electrical energy management. It is mainly responsible for identifying the CPU power supply amplitude, generating the corresponding short-distance wave, and promoting the power output of the back-end circuit. Commonly used power management chip are HIP630IS653RT923ADP316KA7500, TL494, etc.
4, there is a timing chip, 1 can achieve charging in the desired period of time, and some places can save money with half the price of electricity. 2 Can stop charging after full, to avoid endless charging resulting in battery water loss and life shrinkageIt's short.
1, the power management chip model table is as follows: PIC24F32KA301. PIC24F16KA301. PIC24F16KA101. PIC18F14K22. PIC18F14K50. PIC16F1829. PIC16F1509. dsPIC33FJ12MC201. PIC24F08KA101. PIC18F13K22. 1PIC18F13K50. 1PIC16F685. 1PIC16F689. 1PIC16F690.
2, Power distributor: The power distributor is used to distribute the main power to multiple components in the system. They typically have multiple outputs, each of which can be controlled independently to meet the power needs of different components. System-level Power Management Unit (SPM) : The System-level power management unit (SPM) is a highly integrated power management solution that integrates multiple power management functions such as voltage regulation, battery charging, load switching, and power distribution.
3. FeetThere are many models of power management chips, the following are some common models: AP2141:14-pin power management chip, with overvoltage protection, overcurrent protection and short circuit protection functions. TPS2113A: Dual channel 14-pin power management chip for applications such as battery switching, power selection, and power management. RT9711:14 pin power management chip, with overvoltage protection, undervoltage protection and overcurrent protection functions.
4, TI UCC12050: This is a high performance, low cost current mode PWM controller for offline and DC-DCConverter application. Its features include adjustable frequency, cycle by cycle current limitation, etc. TI UCC28950: This is a chip for high performance, low standby power offline switching power supply. It integrates a variety of protection functions, such as overvoltage protection, undervoltage protection and so on.
