Texas Instruments LMR14050-Q1 | Demoboard TIDA-00887

Description

The TIDA-00887 is comprised of a two-port USB 2.0 hub with short-to-battery (STB) and short-circuit protection on both downstream ports provided by the TPD3S716-Q1. Both downstream ports are configured either as a custom divider mode or a dedicated charging port (DCP) provided by the TUSB4020BI-Q1 USB2.0 hub if no upstream device is connected. When an upstream is connected, the TUSB4020 hub will support charging via CDP. The ports automatically switch between divider mode, CDP mode, and DCP mode depending on the portable devices connected in order to provide the fastest charging rate to the connected device.
