BQ77915: 如何理解BQ77915的hibernate mode和shutdown mode

Part Number: BQ77915

你好,

hibernate mode是一个怎么样的模式。哪些资源是开的,哪些是关的?进入hibernate mode的条件是什么?

shutdown mode是一个怎么样的模式。与hibernate mode相比,有什么不同?

Regards

Alex Chen

  • 您好,Most of the internal circuitry is turned off in HIBERNATE mode to save power. Charge and discharge FETs are turned off and all fault protections are disabled.

    进入hibernate mode的条件

    When the PRES pin is left floating (the system or charger is not connected to the pack), the load is not connected, and the device is not in any fault condition, the device enters HIBERNATE mode after tPRES_DEG_ENT time.

    shutdown mode更省电,两者recover方式不一样。
