STUSBCD01B集成電路（IC）的專用規(guī)格書PDF中文資料

STUSBCD01B屬于集成電路（IC）的專用。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的STUSBCD01B專用該系列產(chǎn)品可提供所需的功能，用以將信息源/信宿連到各種復(fù)雜或范圍狹窄應(yīng)用中的傳感器、變送器、致動(dòng)器、傳輸介質(zhì)或其他此類端點(diǎn)。例如，汽車安全氣囊驅(qū)動(dòng)器、車身控制和信息娛樂總線、自適應(yīng)電纜均衡器、智能卡等等。

Description

The STUSBCD01B is a USB charger detection IC which can detect dedicated USB chargers, Host/Hub chargers or standard host ports connected to the USB DP/DM data lines.

The device implements two different detection methods in order to be able to distinguish between a dedicated charger and a Host/Hub charger.

Operation is controlled through three general purpose I/O pins; a hardware open drain detection output is also available.

An internal regulator provides the 1.8 V supply voltage for the internal blocks and state machine while a clamping device prevents VBUS voltage from going over 6 V (typ.).

The STUSBCD01B is available in a 12 bumps Flip-Chip 0.4 mm pitch package.
