Preliminary SLG55596 USB Host Charger Identification Analog Switches General Description Pin Configuration - SLG55596 The SLG55596 is a USB device that combines high speed CEN 1 8 CB USB switches with a USB host charger (dedicated charger) identification circuit. The device supports both the latest USB DM 2 7 TDM Battery Charging Specification Revision 1.2 including data 3 6 DP TDP contact detection and a set resistor bias for Apple* compliant SMART-CDP VDD 45 devices as well as legacy USB D+/D- short detection using Thermal Pad data line pull-up. TDFN-8 connected to GND The SLG55596 can also support CDP mode (FAST charging (Top View) and data communication available mode if smartphone can support CDP mode). * Apple iPhone, iPad and iPod are trademarks of Apple Inc., registered in the The SLG55596 can also support low speed / full speed U.S. and other countries. mouse/keyboard wake-up from S3 mode. ** Samsung Galaxy Tab are trademarks of Samsung Electronics, registered in Korea and other countries.
