The TUSB4020BI-Q1 is a two-port USB 2.0 hub, which provides USB high-speed/full-speed connections on the upstream port and high-speed, full-speed, or low-speed connections on the two downstream ports. When the upstream port is connected to an electrical environment that supports high-speed and full-speed/low-speed connections, high-speed and full-speed/low-speed USB connectivity is enabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports full-speed/low-speed connections, high-speed connectivity are disabled on the downstream ports.
The TUSB4020BI-Q1 supports per port or ganged power switching and overcurrent protection.
An individually port power controlled hub switches power on or off to each downstream port as requested by the USB host. Also when an individually port power controlled hub senses an overcurrent event, only power to the affected downstream port is switched off.
A ganged hub switches on power to all the downstream ports when power is required to be on for any port. The power to the downstream ports is not switched off unless all ports are in a state that allows power to be removed. Also when a ganged hub senses an overcurrent event, power to all downstream ports is switched off.
The TUSB4020BI-Q1 provides terminal strap configuration for some features (including battery charging support) and customization through OTP ROM, I2C EEPROM or an I2C/SMBus target interface for PID, VID, custom port and phy configurations. Custom string support is also available when using an I2C EEPROM or the I2C/SMBus target interface.
The device is available in a 48-pin HTQFP package and is designed for operation over the industrial temperature range of –40°C to 85°C.

TIDA-00887 — 具有電池短路保護的車用 2.4A 雙連接埠 USB 集線器參考設計
TIDA-00887 由雙埠 USB 2.0 集線器組成，具有由 TPD3S716-Q1 提供的兩個下游連接埠上的電池短路 (STB) 和短路保護功能。如果未連接上游裝置，則兩個下游連接埠均可配置為自訂分壓器模式或由 TUSB4020BI-Q1 USB 2.0 集線器提供的專用充電連接埠 (DCP)。 連接上游時，TUSB4020 集線器支援透過 CDP 進行充電。連接埠會根據所連接的可攜式裝置自動在分壓器模式、CDP 模式和 DCP 模式之間切換，以便為所連接的裝置提供最快的充電速率。
此參考設計與 TIDA-00845 類似，但移除了系統內 STB 模擬器，並新增了 2.4A (...)
