Functional Pin Descriptions
BOOT
Connect BOOT to a 0.1μF ceramic capacitor to the PHASE
pin and connect to the cathode of the bootstrap Schottky
diode.
UGATE
UGATE is the high side MOSFET gate drive output.
SGATE
SGATE is the AC adapter power source select output. The
SGATE pin drives an external P-MOSFET used to switch to
AC adapter as the system power source.
BGATE
BGATE power source select output. This pin drives an
external P-channel MOSFET used to switch the battery as
the system power source. When the voltage at the CSON
pin is higher than the AC adapter output voltage at DCIN,
BGATE is driven to low and selects the battery as the power
source.
LGATE
LGATE is the low side MOSFET gate drive output; swing
between PGND and VDDP.
