The TPS2111APWRG4 can deliver up to 2.5A of current from the USB port, but this is limited by the thermal performance of the package and the PCB design. It's recommended to keep the current below 2A for reliable operation.
The TPS2111APWRG4 is a USB-C power switch, but it does not have built-in Power Delivery (PD) functionality. You'll need to use an external PD controller, such as the TPS65982, to implement PD functionality.
The EN (Enable) pin is used to turn the device on or off. When EN is high, the device is enabled, and when EN is low, the device is disabled. You can use the EN pin to control the power state of the USB port, for example, to implement power management or to turn off the port when not in use.
The TPS2111APWRG4 has built-in OCP and SCP features. When an overcurrent or short-circuit condition is detected, the device will automatically limit the current or shut down the port to prevent damage. You can also use the FLAG pin to monitor the fault status and take external action if needed.
The TPS2111APWRG4 is a high-power device, and proper layout and thermal design are crucial for reliable operation. TI provides a recommended layout and thermal design guide in the datasheet and application notes. It's essential to follow these guidelines to ensure the device operates within its thermal limits.
