EC49021AS/AD Dual/Single USB Charger Port Controller DESCRIPTIONS The EC49021A are USB dedicated charging port (DCP) controllers. An auto-detect feature monitors USB data line voltage, and automatically provides the correct electrical signatures on the data lines to charge compliant devices among the following dedicated charging schemes: ■ Divider 1 DCP, required to apply 2 V and 2.7 V on the D+ and D– Lines respectively. ■ Divider 2 DCP, required to apply 2.7 V and 2 V on the D+ and D– Lines respectively. ■ BC1.2 DCP, required to short the D+ Line to the D– Line ■ Chinese Telecom Standard YD/T 1591-2009 Shorted Mode, required to short the D+ Line to the D– Line. ■ 1.2 V on both D+ and D– Lines. FEATURE ■ Supports USB DCP Shorting D+ Line to D- Line per USB Battery Charging Specification, Revision 1.2(BC1.2). ■ Supports Shorted Mode (Shorting D+ Line to D- Line) per Chinese Telecommunication Industry Standard YD/T 1591-2009. ■ Supports USB DCP Applying 2.7 V on D+ Line and 2 V on D- line (or USB DCP Applying 2 V on D+ Line and 2.7 V on D– Line). ■ Supports USB DCP Applying 1.2 V on D+ and D– Lines. ■ Automatically Switch D+ and D- Lines Connections for an Attached Device. ■ Dual USB Port Controller, EC49021AD. Single USB Port Controller, EC49021AS. ■ Operating Range: 4.5 V to 5.5 V. ■ Available in SOT23-6 Package. APPLICATION ■ Vehicle USB Power Charger ■ AC-DC Adapter with USB Port ■ Other USB charger ORDERING INFORMATION EC49021AX XX X R：Tape & Reel S：Single port D：Dual port B3：SOT23-6 E-CMOS Corp.
