Part Number: BQ25792 Other Parts Discussed in Thread: TPS65987D , BQ25723 , 各位工程师你们好:
我原来使用TPS65987D+BQ25723做了一套充电电路,但这个组合无法用外部LED灯指示充电状态。
原来设计是使用TPS65987D获取PD协议供电,然后987D的I2C配置BQ25723充电电压/电流
设计条件是:通过 987D控制,到BQ 最大供电20V/3A,最小5V/1A;电池充电电压8.7V,最大充电电流5A.
现在保持使用987D快充协议芯片不变条件下…
您好, There should not be 9V on REGN. I notice that the COMP1 and COMP2 compensation networks are not following the guidelines as specified on the datasheet section 9.3.13. Also, the ILIM_HIZ should be powered from a voltage divider network from VAA, not…
您好,BQ25703A can operate in forward mode or reverse OTG mode. BATFET is on when in charge or in OTG. If you want more flexible control of the BATFET, suggest BQ25723.
