General Description

The SLG55587/SLG55587A 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 SLG55587/SLG55587A can also support Apple IPAD2

@ 2 A charging current.

The SLG55587/SLG55587A can also support low speed / full

speed mouse/keyboard wake-up from S3 mode.
