STUSBCD01B USB charger detection interface

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. Table 1. Device summary Order code STUSBCD01BJR Pac.
