Application Notes
- Automatic AC/USB Detection in bq24050/2/5 Using D+/D- pinsPDF, 134 Kb, File published: Jan 25, 2010
Modern day electronic devices, such as cell phones and MP3 players, can usually be powered with either an adapter or USB source through a single input connector using a mini USB cable. For a simple charger, without separate power paths for the system and the battery, the system (including the device transceiver) is powered directly from the battery. If the battery is deeply discharged, it has to - Selecting the Best bq2404x/5x/9x Single Cell Battery Charger for your ApplicatioPDF, 38 Kb, File published: Nov 29, 2012
