TPS2112PWG4 Frequently Asked Questions (FAQs)
The TPS2112PWG4 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 TPS2112PWG4 is a USB-C power switch, but it does not have built-in PD controller functionality. You'll need to use an external PD controller, such as the TPS65982, and connect it to the TPS2112PWG4's control pins to enable PD functionality.
The EN (enable) pin is used to turn the TPS2112PWG4 on and off. When EN is high, the device is enabled, and when EN is low, the device is disabled. You can use this pin to control the power state of the USB port, for example, to implement power-saving modes or to disconnect the USB port during system shutdown.
The TPS2112PWG4 has built-in OCP and SCP features. When an overcurrent or short-circuit condition is detected, the device will automatically limit the current or disconnect the USB port. You can adjust the OCP threshold using external resistors, and you can also use the FAULT pin to monitor the device's fault status.
Yes, the TPS2112PWG4 can be used with a USB hub or other downstream devices. However, you'll need to ensure that the total current drawn from the USB port does not exceed the device's maximum current rating. You may also need to add additional circuitry to handle the increased current requirements.
