USB Host Charger Identification

Overview

The SLG55594A is a USB device that combines high speed USB switches with a USB host charger (dedicated charger) identification circuit. The device supports both the latest USB Battery Charging Specification Revision 1.2 including data contact detection and a set resistor bias for Apple* compliant devices as well as legacy USB D+/D- short detection using data line pull-up. The SLG55594A can also support CDP mode (FAST charging and data communication available mode if smartphone can support CDP mode.) The SLG55594A can also support low speed / full speed mouse/keyboard wake-up from S3 mode.
