The basic implementation of the bq77905 3-5S Low Power Protector for lithium ion batteries uses singlecharge and discharge FETs for current control. This document shows circuit implementation examples ofdriving multiple charge and discharge FETs when using the bq77905. The schematic examples and testresults will help the battery electronics designer when designing a pack with multiple FETs f - BQ77905 Design Considerations in High-Current ApplicationsPDF, 1.8 Мб, Файл опубликован: 5 дек 2016
The BQ77905 is a 3-5S low-power protector for lithium-ion batteries that controls the charge anddischarge FETs for current control. In some cases, the charge and discharge current path is required tohandle a continuous high-current that causes heat and component problems. This document provides anexample of the BQ77905 with a 50-A current path for charge and discharge. The design considerati - bq77905 20S Cell Stacking Configuration (Rev. A)PDF, 395 Кб, Версия: A, Файл опубликован: 28 июл 2017
The bq77905 is a 3–5S Low Power Protector with easy stacking capabilities for higher than 5S cell batterypacks. This document provides an example for setting up a stacking configuration with the bq77905 andexhibits detailed analysis of the stacking functionality. - bq77905 Separate Current Paths (Rev. A)PDF, 253 Кб, Версия: A, Файл опубликован: 7 июл 2016
The basic implementation of the bq77905 3-5S Low Power Protector for lithium-ion batteries uses a singleseries current path for charge and discharge. In some system designs it is desirable to have separatecurrent paths for charge and discharge. This document shows circuit implementation examples ofseparate charge and discharge paths when using the bq77905. The schematic examples and test res - bq77905 Shutdown for Current ReductionPDF, 231 Кб, Файл опубликован: 21 июл 2017
The bq77905 3-5S Low-Power Protector for lithium-ion batteries features a low 6-ОјA typical supply currentto extend battery life. Power tools or other applications where the battery is in storage or unused for longperiods may want to prevent battery discharge during idle times. The schematic examples and test resultsin this document help the battery electronics designer when implementing a ci
