SLG55596A USB Host Charger Identification Analog Switches General Description Pin Configuration - SLG55596A The SLG55596A is a USB device that combines high speed CEN 1 8 CB USB switches with a USB host charger (dedicated charger) DM 2 7 identification circuit. The device supports both the latest USB TDM Battery Charging Specification Revision 1.2 including data DP 3 6 TDP contact detection and a set resistor bias for Apple* compliant VDD SMART-CDP 45 devices as well as legacy USB D+/D- short detection using Thermal Pad data line pull-up. TDFN-8 connected to GND The SLG55596A can also support CDP mode (FAST charging (Top View) and data communication available mode if smartphone can support CDP mode). The SLG55596A can also support low speed / full speed * Apple iPhone, iPad and iPod are trademarks of Apple Inc., registered in the mouse/keyboard wake-up from S3 mode. U.S. and other countries.
