Apple iPhone charger teardown: quality in a tiny expensive package I've put together an approximate schematic showing the charger circuit. IMO just about all of these USB "chargers" are constant voltage power supplies. (IIRC the USB spec calls for 5 V +/- 5% or so.) Basically a mini version of the average desktop PC power supply.. 2.1 Schematic Figure 1: USB Battery Charging Example battery depending on the power source detected and the associated current limit of the power source. The charge rate of the battery is defined by the resistance connected to the PROG pin of FTAN_175 Battery Charger Detection over USB with-X Devices Version 1.1 Document Reference No. Universal Serial Bus (USB) is an interface to establish communication between devices and a host controller Due to the ability to supply power to the preipheral devices USB is often used as a power charger for portable devices. An USB system architecture consists of a host controller, a USB ports, and multiple connected devices..

Laptops, lights, phones, tablets, televisions, radios, speakers, and more. Compatible with any device that requires 90 watts or less through a standard wall plug.. When USB power is applied this circuit will turn off Q1, and as long as (V usb – D1 V F) is above (V bat – Q1 V SD) then the load will instead use power from USB through D1. This allows the battery to charge normally without any outside disturbances..

drop across the power MOSFET of the charger. In this mode, the L6924D charges the battery with the same three phases as in linear mode, but power dissipation is. USB Charger This is a portable battery powered USB charger circuit. This circuit is able to charge your PDAs, Ipods, Mp3 players and any device that plug in to a computer USB to charge..
