USB Double Charger – ULA919

Functional Description

• Two mobile devices can be charged simultaneously
• This chargers are redundant and independent each other (A shortcut by one doesn’t influence the charging process by the other
• Standard USB connector outputs,
• Both output can supply 2.5Amp current maximum at 5V,
• If the temperature get higher then the expected 85 C, the circuit will cut trough the DC-DC converter, until the temperature reducing below the critical level.
• The input can absorb short (for milisecs) DC peaks up to 500 V. Easy to install
• Supported mobile devices by charger profile identification
o iPod, iPhone, iPad,
o Android phones and tabs
• Supported Charge Profiles:
1. Divider 1 DCP, (required to apply 2 V and 2.7 V on D+ Line on the D+ and D– Lines) 2. Divider 2 DCP, required to apply 2.7 V and 2 V on the D+ and D– Lines
3. Divider 3 DCP, required to apply 2.7 V and 2.7 V on the D+ and D- Lines
4. BC1.2 DCP, required to short the D+ Line to the D– Line
5. Chinese Telecom Standard YD/T 1591-2009 Shorted Mode, required to short the + Line to the D– Line
6. 1.2 V on both D+ and D– Lines – Automotive environment compatible design – Overcurrent protection, overvoltage protection, thermal protection
