SE100
QC2.0 Interface Module
General Description
SE100 is designed to support QuickCharge QC 2.0
(QC2.0) specifications. It is a low-cost solution to
support QC2.0 functions. SE100 incorporates all
necessary functions to add QC2.0 capability to
standard Adaptor designs, Portable Battery designs,
and Car-charger designs.
SE100 supports the full output voltage range of either
Class A or Class B. Optionally Class B can be
inhibited for protecting the battery charger from
accidental damage.
SE100 automatically detects whether a connected
Powered Device (PD) is QC2.0 capable before
enabling output voltage adjustment. If a PD that is not
compliant to QC2.0 is detected the SE100 disables
output voltage adjustment to ensure safe operation
with legacy 5 V only USB PDs.
