9.4.1.4 HIBERNATE Mode

If the PRES pin is left floating, the device enters HIBERNATE mode operation. In this mode, all fault detection and cell balancing is deactivated and the CHG and DSG drivers are turned off to reduce power consumption to ultra-low levels. This mode of operation is recommended when the battery packs are in shipping or storage. The device can be brought back to NORMAL mode by driving PRES high.
