SE100B
QC2.0 Interface Module
General Description
SE100B is designed to support QuickCharge QC
2.0 (QC2.0) specifications. At the same time, it
also supports Apple, Samsung and BC1.2 DCP
(Dedicated Charging Port) compliant devices.
It is a low-cost solution to support QC2.0
functions, and various other DCP interfaces
devices. SE100B incorporates all necessary
functions to add QC2.0 capability to standard
Adaptor designs, Portable Battery designs, and
Car-charger designs.
SE100B supports the full output voltage range of
either Class A or Class B. Optionally Class B can
be inhibited for protecting the battery charger
