BQ27546-G1: bq27546的HIBERNATE模式

Part Number: BQ27546-G1

我们使用BQ27546-G1的时候,设置 Hibernate Voltage =3V,测试的时候我们设定Vbat=2.8V,BQ27546-G1的耗电在25uA左右,比规格书中的8uA大了很多,认为BQ27546-G1没有进入Hibernate 模式,请教一下原因。或者BQ27546-G1进入Hibernate 的条件是什么?

  • 您好,手册给出的功耗是芯片的功耗,在板子的上的功耗会稍大。Hibernate 模式的进入请参考下面内容

    Exit From WAIT_HIBERNATE Cell relaxed AND | AverageCurrent() | < Hibernate Current

    OR Cell relaxed AND VCELL < Hibernate Voltage
