Abstract

 

The nLTS family of products permits the charging of select Lenovo mobile devices while 
simultaneously interacting with USB 2.0 accessories.  
 
This product’s mode of operation charges your mobile device battery to 100% as long as external 
power is attached. This mode of operation supports Docking Detect, which ensures the mobile 
device enters the correct state during a “hot connect” to the LAVA product.  
 
This document describes the connectors and configuration options for the product line. All 
supported devices use the Micro-USB interface.
