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.
