BAT (Pin 31): Battery Voltage Sense Input. This pin is used
to monitor the battery and control charging voltage through
an internal resistor divider connected to this pin that is
disconnected in shutdown mode. Also provides a control
input for battery ideal diode functions. Pin should be Kelvin-
connected to battery to avoid voltage drop errors.
DCHFET (Pin 32): Drives the Gate of an External N-MOSFET.
Used to drive energy into the battery side of the high ef-
ciency switch mode converter during low loss calibration
discharge of the battery. Provides synchronous rectication
during battery charging.
CHGFET (Pin 33): Drives the Gate of an External N-
MOSFET. Used to drive energy into the supply side of
the high efciency switch mode converter during battery
charging. Provides synchronous rectication during low
loss calibration mode.
VDD (Pin 34): Bypass Capacitor Connection for Internal
VDD Regulator. Bypass at pin with 100nF low ESR capaci-
tor to GND.
BATID (Pin 35): Drives the Gate of the Battery P-MOSFET
Ideal Diode. Controls low loss ideal diode between the
battery and backup load when in backup mode. When not
in backup mode, the P-MOSFET is turned off to prevent
battery power from back driving into main power.
NC (Pin 36): No Connect.
DCOUT (Pin 37): System Power Output Voltage Monitor
Input. Provides a control input for supply input ideal diode
and battery ideal diode functions. Also supplies power to the
IC. Bypass at pin with 100nF low ESR capacitor to GND.
INID (Pin 38): Drives the Gate of the Supply Input P-MOSFET
Ideal Diode. Controls low loss ideal diode between the sup-
ply input and backup load when not in backup mode.
Exposed Pad (Pin 39): Ground. The Exposed Pad must
be soldered to the PCB.
