CHRG (Pin 7): Open-Drain Charge Status Output. The
CHRG pin indicates the status of the battery charger. Four
possible states are represented by CHRG: charging, not
charging (or float charge current less than programmed
end of charge indication current), unresponsive battery and
battery temperature out of range. CHRG is modulated at
35kHz and switches between a low and a high duty cycle
for easy recognition by either humans or microprocessors.
CHRG requires a pull-up resistor and/or LED to provide
indication.
GATE (Pin 8): Ideal Diode Amplifier Output. This pin controls
the gate of an external P-channel MOSFET transistor used
to supplement the internal ideal diode. The source of the
P-channel MOSFET should be connected to VOUT and the
drain should be connected to BAT.
BAT (Pin 9): Single Cell Li-Ion Battery Pin. Depending on
available power and load, a Li-Ion battery on BAT will either
deliver system power to VOUT through the ideal diode or
be charged from the battery charger.
VOUT (Pin 10): Output voltage of the switching PowerPath
controller and input voltage of the battery charger. The
majority of the portable product should be powered from
VOUT. The LTC4088-1/LTC4088-2 will partition the available
power between the external load on VOUT and the internal
battery charger. Priority is given to the external load and
any extra power is used to charge the battery. An ideal
diode from BAT to VOUT ensures that VOUT is powered even
PI FU CTIO S
if the load exceeds the allotted power from VBUS or if the
VBUS power source is removed. VOUT should be bypassed
with a low impedance multilayer ceramic capacitor.
VBUS (Pin 11): Input voltage for the switching PowerPath
controller. VBUS will usually be connected to the USB port
of a computer or a DC output wall adapter. VBUS should
be bypassed with a low impedance multilayer ceramic
capacitor.
SW (Pin 12): The SW pin delivers power from VBUS to
VOUT via the step-down switching regulator. An inductor
should be connected from SW to VOUT. See the Applica-
tions Information section for a discussion of inductance
value and current rating.
D0 (Pin 13): Mode Select Input Pin. D0, in combina-
tion with the D1 pin and the D2 pin, controls the current
limit and battery charger functions of the LTC4088-1/
LTC4088-2 (see Table 1). This pin is pulled low by a weak
current sink.
D1 (Pin 14): Mode Select Input Pin. D1, in combination
with the D0 pin and the D2 pin, controls the current limit
and battery charger functions of the LTC4088-1/LTC4088-
2 (see Table 1). This pin is pulled low by a weak current
sink.
Exposed Pad (Pin 15): GND. Must be soldered to the
PCB to provide a low electrical and thermal impedance
connection to ground.
