1 / 8 page  HM100 QC2.0 Interface Module General Description HM100 is designed to support QuickCharge QC 2.0 (QC2.0) specifications. It is a low-cost solution to support QC2.0 functions. HM100 incorporates all necessary functions to add QC2.0 capability to standard Adaptor designs, Portable Battery designs, and Car-charger designs. HM100 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. HM100 automatically detects whether a co nnected 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 HM100 disables output voltage adjustment to ensure safe operation with legacy 5 V only USB PDs. Pin Configuration Features Fully supports Quick Charge 2.0 specification Class A: 5 V, 9 V, and 12 V output voltage Class B: 5 V, 9 V, 12 V, and 20 V output voltage USB battery charging specification revision 1.2 compatible Automatic USB DCP shorting D+ to D- line Default 5 V mode operation Very low power consumption Less than 1 mW at 5 V output Fail safe operation Adjacent pin-to-pin short-circuit fault Open circuit pin fault Applications Adaptors for smart phones, tablets, netbooks, digital cameras, and bluetooth accessories Portable Battery Packs supporting QC.20 functions Car Cargers supporting QC2.0 functions Ogther USB power output ports supporting QC2.0 functions Page 1 |
