LD8108A Overview
The LD8108A is an AC/DC Speedy Charge™ controller for Qualm® Quick Charge™ 2.0 (QC2.0) USB interface receiver for High Voltage Dedicated Charging Port (HVDCP) charger solution. The device can receive QC2.0 signal from D+ and Dof USB interface for HVDCP control. Paired with LD5718A series primary-side regulation (PSR) controllers, LD8108A will send the digital data by a single photocouplier to PSR controller and change output regulation. LD8108A provides typical 300mA discharging current for output from HVDCP voltage to 5V in order to meet a short discharge time. Active dummy load function is built in LD8108A to keep output regulation while in no load condition. LD8108A implements temperature detection function which will send digital data to shutdown PSR controller during over temperature condition.
