TYPICAL APPLICATION
FEATURES
DESCRIPTION
Dual-Input Power Manager/
3.5A Li-Ion Battery Charger with
I2C Control and USB OTG
The LTC®4155 is a 15 watt I2C controlled power manager
with PowerPath™ instant-on operation, high efficiency
switching battery charging and USB compatibility. The
LTC4155 seamlessly manages power distribution from
two 5V sources, such as a USB port and a wall adapter,
to a single-cell rechargeable Lithium-Ion/Polymer battery
and a system load.
The LTC4155’s switching battery charger automatically
limits its input current for USB compatibility, or may
draw up to 3A from a high power wall adapter. The high
efficiency step-down switching charger is designed to
provide maximum power to the application and reduced
heat in high power density applications.
I2C adjustability of input current, charge current, battery
float voltage, charge termination, and many other param-
eters allows maximum flexibility. I2C status reporting of
key system and charge parameters facilitates intelligent
control decisions. USB On-The-Go support provides 5V
power back to the USB port without any additional com-
ponents. A dual-input, priority multiplexing, overvoltage
protection circuit guards the LTC4155 from high voltage
damage on the VBUS pin.
The LTC4155 is available in the low profile (0.75mm)
28-lead 4mm × 5mm QFN surface mount package.
