UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
The SYS pin is the output of the power path. When TPS6507x is turned off and there is no voltage at AC or USB, the SYS output is disconnected internally from the battery. When TPS6507x is turned on by pulling PB_IN =LOW, the voltage at SYS will ramp with a soft-start. During soft start, the voltage at SYS is ramped with a 30-mA current source until the voltage reached 1.8 V. During the soft start, the SYS pin must not be loaded by an external load.
