The TPD4S214 is a single-chip protection solution for USB On-the-Go (OTG) and other current limited USB applications. This device includes an integrated low RDS(ON) N-channel current limited switch for the OTG current supply to peripheral devices. TPD4S214 offers low capacitance transient voltage suppression (TVS) electrostatic discharge (ESD) clamping diodes for the D+, D–, and ID pins for both USB2.0 and USB3.0 applications. The VBUS pin can handle continuous voltage ranging from –7 V to 30 V. The over voltage lock-out (OVLO) at the VBUS pin ensures that if there is a fault condition at the VBUS line, TPD4S214 is able to isolate it and protect the internal circuitry from damage. Similarly, the under voltage lock out (UVLO) at the VOTG_IN pin ensures that there is no power drain from the internal OTG supply to external VBUS if VOTG_IN droops below a safe operating level. When EN is high, the OTG switch is activated and the FLT pin indicates whether there is a fault condition. The soft start feature waits 16 ms to turn on the OTG switch after all operating conditions are met.

TPD4S214EVM — USB OTG 配套裝置評估模組
TPD4S214EVM 提供完整的 TPD4S214 功能。根據跨接器配置，VOTG_IN 可透過標示為 USB_IN 的 USB Type-A 連接器，或標示為 VOTG_IN 的香蕉插孔供電。VBUS 可輸出至標示為 USB_OUT 的 Micro USB-B 連接器，或標示為 VBUS_OUT 的雙接腳端子區塊。此配置可在不使用昂貴的擴充板情況下進行裝置測試；當然，也可搭配一至兩片分接板使用。D+/D- 線路僅能透過 USB 連接器進行特徵分析。提供測試點以監測 DET、EN 與 FLT 邏輯接腳。VBUS 電流限制可透過選擇 ADJ_SEL 跨接器進行調整。R3 (...)
