This application report discusses the four design changes made to the bq24032 IC and implemented in the bq24032A device. - Adjustable/Variable Clock Timer For bq24030/2/5 Li-Ion One-Cell Battery ChargersPDF, 151 Кб, Файл опубликован: 13 сен 2005
The bq2403x Battery Charger and Dynamic Power Path Management (DPPM) IC is a highly integrated IC which minimizes the required wall adapter size by reducing the battery charging current during peak current demands by the system. Typically, a 5-hour charge timer is used to limit the charge time on the battery as a safety feature. Because the charging current can be reduced at any time for any durat - Dynamic Power Path Management Simplifies Battery Charging from Solar PanelsPDF, 666 Кб, Файл опубликован: 17 окт 2006
The Texas Instruments bq2403x family of linear charge regulators were originally designed to charge single-cell Li-ion batteries from an AC adapter or USB port. However, these ICs also lend themselves well to applications powered by solar panels. - Dynamic Power-Path Mgmt & Dynamic Power MgmtPDF, 96 Кб, Файл опубликован: 2 янв 2007
Dynamic power-path management (DPPM) and dynamic power management (DPM) are two similar types of integrated power management ICs that combine the task of charging a single-cell Li-ion battery and powering the system. Both topologies reduce the battery charging current to give the system priority when the adaptor has reached its output current rating. The bq2403x family and TPS65800 IC use the DPP - Q4 2007 Issue Analog Applications Journal (Rev. A)PDF, 316 Кб, Версия: A, Файл опубликован: 14 ноя 2007
