Automotive 2.4A Dual-Port USB Hub Reference Design With Short-to-Battery Protection
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 USB 2.0 hub if no upstream device is connected. When an upstream is connected, the TUSB4020 hub supports 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.
This reference design is similar to the TIDA-00845, however, it removes the in-system STB simulator and adds functionality for 2.4-A charging and automatic charge detection.
Features
- Fully functional USB hub with short-to-battery (STB) protection and BC 1.2 charge detection
- Supports USB 2.0 high-speed data rates
- Adjustable overcurrent protection current limit up to 2.4 A
- IEC 61000-4-2 (Level 4) and ISO 10605 system-level ESD protection on VBUS_CON, DP/DM
- STB protection (up to 18 V) on VBUS_CON, VD+, VD-
- Short-to-ground protection on VBUS_CON for both downstream ports
