SE100-HF

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.
