BQ40Z50-R2: sleep模式下功耗测试

Part Number: BQ40Z50-R2
Other Parts Discussed in Thread: BQ40Z50

BQ40Z50的手册中sleep睡眠模式功耗75uA,测试条件是什么,上位机如何配置?硬件电路哪些需要断掉?按手册应用电路做的PCB,测试其在sleep模式下的功耗,实际测量是手册上的2倍,能指导一下sleep模式功耗具体是如何测量的吗

  • 您好,Current consumption values during sleep mode of the bq40z50 may vary based upon layout and other circuit considerations.

    As noted, with TA = 25 degC and VCC = 14.4 V, typical sleep mode is 75 uA with CHG off, DSG on, no SBS communication, and 52 uA with CHG off, DSG off and no SBS communication.

    An empirical approach may be best for determining specific VCC and temperature operating ranges for your device.
