Charge path configured as Serial Path (J4 needs to be shorted and J3 open)
Charge path configured as Single path (J3 needs to be shorted and J4 open)
Battery FET controlled by the GBAT pin
GBAT grounded when the charge path is configured as Single. J4 must be open
Battery FET not controlled by GBAT. J3 must be shorted
Battery FET controlled by GBAT pin. Charge path configured as Serial
No external PNP is connected to BP
Connects external PNP to BP to avoid excess on-chip power dissipation at high
loads and large differentials between BP and VUSB2 output settings
PWRON1 pin can be controlled thru switch SW1 only
PWRON1 pin can be externally controlled by an MCU (e.g. USBCOMDGL board)
connected to the J11 connector
VBUS disconnected from J13 connector
VBUS pin is connected to the J13 connector to be supplied from the USB cable
connected to an MCU board (e.g. USBCOMDGL board), or to supply a USB
cable in OTG mode
VBUS is disconnected from the J25 connector
VBUS voltage supplied from a USB cable connected to the J25 connector (e.g.
USB port/hub/charger), or to supply 5.0 V in USB OTG mode
No external PNP is connected to BP
Connects external PNP to BP to avoid excess on-chip power dissipation at high
loads and large differentials between BP and VGEN2 output settings
SPIVCC is supplied by SW5. J52 must be open
SPIVCC is supplied by VDAC. J52 must be open
SPIVCC is supplied by either SW4A or the MCU board (e.g.
USBCOMDGLEVME board)
TRICKLESEL pin is connected to VCOREDIG. The switching charger is enabled
in CC mode for trickle charging at 325 mA
TRICKLESEL pin is connected to ground. The Itrickle2 current uses the internal
trickle charge path
TRICKLESEL pin floating. The switching charger is enabled in CC mode for
trickle charging at 550 mA
VBUS is disconnected from the J23 connector
VBUS voltage is supplied from a mini B USB cable connected to the J23
connector (e.g. USB port/hub/charger), or to supply 5.0 V in USB OTG mode
PRETMR pin is connected to VCOREDIG. Trickle pre-charge timer is preset to
5.5 hrs
PRETMR pin is connected to ground. Trickle pre-charge timer is preset to 4.5 hrs
PRETMR pin is floating. Trickle pre-charge timer is preset to 6.5 hrs
