STUSBCD01B中文资料USB充电器检测接口数据手册ST规格书

描述 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.
