"BQ25970 100% Original Charging iC Chip For Tecno Infinix Oppo Vivo Redmi BAT temp thermistor monitoring (hot/cold profile), IC thermal regulation, Input OVP, Integrated ADC The BQ25970 is a highly-integrated switch-mode battery charge management and system power path management device for single cell Li-Ion and Li-polymer batteries in a wide range of tablet and other portable devices. Applications:- Tablet PC and Smart Phone Portable Audio Speaker Portable Media Players Internet Devices The BQ25970 is available in a 52-pin, - Features: - Brand new replacement BQ25970 IC chip for Nintendo Switch consoles. - Can repair issues with battery charging. - Located on the mainboard of the Switch console. - SMD part - requires high level of soldering skills. - Requires internal fitting - Console must be opened to install. Description: The BQ25970 is a 97% efficient, 8-A battery charging solution using a switched cap architecture. This architecture and the integrated FETs are optimized to enable a 50% duty cycle, allowing the cable current to be half the current delivered to the battery, reducing the losses over the charging cable as well as limiting the temperature rise in the application. The dual-phase architecture reduces the input cap requirements as well as reducing the output voltage ripple. When used with a standard charger such as the BQ2589x, the system enables the fastest charging at the lowest power loss from pre-charge through CC, CV, and termination. The device integrates all the necessary protection features to ensure safe charging, including input over-voltage and over-current protection, output over-voltage and over-current protection, temperature sensing for the battery and cable, and monitoring the die temperature. The device includes a 12-bit effective analog-to-digital converter (ADC) to provide bus voltage, bus current, output voltage, battery voltage, battery current, bus temperature, bat temperature, die temperature, and other calculated measurements needed to manage the charging of the battery from the smart wall adapter or power bank. This replacement BQ25970 battery management chip may resolve battery charging problems on a Nintendo Switch. Requires internal fitting and professional soldering to install, the replacing of a small IC chip should only be done by an experienced electronics engineer."
