PIN FUNCTIONS
PROG (Pin 18): Charge Current Program and Monitor Pin.
A resistor from PROG to GND programs the maximum
batterychargerate.TheLTC4155featuresI2Cprogramma-
bilityenablingsoftwareselectionoffifteenchargecurrents
that are inversely proportional to a single user-supplied
programming resistor.
CHGSNS (Pins 19, 20): Battery Charger Current Sense
Pin. An internal current sense resistor between VOUT
and CHGSNS monitors battery charge current. CHGSNS
shouldbeconnectedtothesourceofanexternalP-channel
MOSFET transistor.
VOUT (Pins 21, 22): Output Voltage of the Switching
PowerPath Controller and Input Voltage of the Battery
Charging System. The majority of the portable product
should be powered from VOUT. The LTC4155 will partition
the available power between the external load on VOUT
and the battery charger. Priority is given to the external
load and any extra power is used to charge the battery. An
ideal diode control function from BATSNS to VOUTensures
that VOUT is powered even 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 of at least 22F.
VBUS (Pins 23, 24, 25): Input Voltage for the PowerPath
Step-Down Switching Regulator and Output Voltage for
the USB On-The-Go Step-Up Switching Regulator. VBUS
may be connected to the USB port of a computer or a DC
output wall adapter or to one or both optional overvolt-
age protection/multiplexer compound transistors. VBUS
should be bypassed with a low impedance multilayer
ceramic capacitor.
SW (Pins 26, 27): Switching Regulator Power Transmis-
sion Pin. The SW pin delivers power from VBUS to VOUT
via the step-down switching regulator and from VOUT to
VBUS via the step-up switching regulator. A 1μH inductor
should be connected from SW to VOUT. See the Applica-
tionsInformationsectionforadiscussionofcurrentrating.
SCL (Pin 28): Clock Input for the I2C Serial Port. The
I2C input levels are scaled with respect to DVCC for I2C
compliance.
GND(ExposedPadPin29):Exposedpadmustbesoldered
to the PCB to provide a low electrical and thermal imped-
ance connection to the printed circuit board’s ground. A
continuousgroundplaneonthesecondlayerofamultilayer
printed circuit board is strongly recommended.
