PRODUCTION DATA
The BATFET functions as a load switch between battery and system when the converter is not running. By changing the state of BATFET from on to off, systems connected to SYS can be power cycled. Any of the following conditions initiates a system power reset:
When BATFET_CTRL_WVBUS is set to 1, system power reset proceeds if either BATFET_CTRL is set to 11 or QON is pulled low for tQON_RST, regardless of whether VBUS is present or not . There is a delay of tBATFET_DLY before initiating the system power reset. If QON is pulled low, there is no delay after the tQON_RST completes, regardless of BATFET_DLY setting.
The system power reset can be initiated from the battery only condition or from the forward charging mode with adapter present.
