| Description & Applications | 1.0A USB Port/Adapter Lithium-Ion/Polymer Battery Charger The AAT3690 BatteryManager is a highly integrated single-cell lithium-ion/polymer battery charger IC designed to operate with USB port and AC adapter inputs. The Adapter charge current rates can be programmed up to 1.0A. In the absence of an adapter and with a USB port connected, the battery can also be charged by USB power. The USB charge current can be programmed up to 1A. A Charge Reduction Loop is also built in to allow users to charge the battery with the available current from a USB port, while keeping the port voltage regulated. In the event of an over-voltage or over-temperature condition, the device will automatically shut down, thus protecting the charging device, control system, and the battery under charge.Applications Cellular Telephones Digital Still Cameras Hand-Held PCs MP3 Players Personal Data Assistants (PDAs) Other Lithium-Ion/Polymer Battery-Powered |
