TUSB9261PVP Working Principle:

The TUSB9261PVP utilizes a three-phase charge control loop. In this mode, the IC automatically and continuously adjusts the output current and voltage according to the resistance of the connecting load. The loops adjust the charge current, charge time, float voltage as well as the bulk voltage. This ensures a safety and efficient charging process.

The IC has a thermal limit control that helps prevent overheating. It decelerates the charging speed when the temperature exceeds a preset limit. In addition, the built-in under-voltage lockout feature prevents from damaging the load by cutting off the output power when input voltage drops below a certain threshold.

TUSB9261PVP also includes over-voltage protection as well as over-current protection. The over-voltage protection helps safeguard the device from damage by shutting off the power when the output voltage exceeds a certain limit. The over-current protection shuts down the supply when an excessive current is drawn.

The IC features a dual-source switching design that allows it to select either an external power adapter or the battery as the charging source. This helps optimize the charging speed and ensures maximum efficiency. Additionally, the TUSB9261PVP has a built-in temperature sensor that can be used to monitor the device temperature.

The TUSB9261PVP is a highly integrated and efficient IC designed for consumer applications that require multiple charging protocols and high integration. Its USB OTG compliant architecture makes it easy for users to connect to products with USB Type-A or Type-B ports. Its advanced features such as temperature sensor, thermal limit control, dual-source switching design, over-voltage protection, and under-voltage lockout help protect the device from damage.
