应用须知
- How to Operate bq20z7x/8x/9x Fuel Gauge and bq24707/25/26 Chrgr w/o Host CntrlrPDF, 153 Kb, 档案已发布: Aug 31, 2011
The bq24707/26/25 chargers and the bq20z7x/8x/9x gas gauges are both SBS-compliant integrated circuits. In this application report, both of these chargers and gas gauges are used together as a nonhost-control, battery charging system. An external regulator, TPS7A49xx, is added to the system to prevent shutting down the system during a deeply discharged state of the battery cells. It provides awa - bq24707/25/26 Input Voltage DPMPDF, 97 Kb, 档案已发布: Jan 26, 2011
The bq24707/25/26 are high-efficiency synchronous battery chargers. They offer low component count for space-constrained, multichemistry, battery-charging applications. They feature real-time system control onthe ILIM pin to limit the charge current. In this application report, the ILIM pin is used to implement real-time, input-voltage, dynamic power management. It is used to reduce the charging - How to Review a Multicell Switching Charger SchematicPDF, 196 Kb, 档案已发布: Sep 21, 2011
This application report provides a checklist for reviewing a switching charger schematic and explains each item in the list.
