LTC4160/LTC4160-1
Switching Power Manager
with USB On-The-Go And
Overvoltage Protection
DESCRIPTION
The LTC
®
4160/LTC4160-1 are high efficiency power man-
agement and Li-Ion/Polymer battery charger ICs. They each
include a bidirectional switching PowerPath™ controller
with automatic load prioritization, a battery charger, and
an ideal diode.
The LTC4160/LTC4160-1’s bidirectional switching regulator
transfers nearly all of the power available from the USB
port to the load with minimal loss and heat which eases
thermal constraints in small spaces. These devices feature
a precision input current limit for USB compatibility and
Bat-Track output control for efficient charging. In addition,
the ICs can also generate 5V at 500mA for USB On-The-
Go applications.
An overvoltage circuit protects the LTC4160/LTC4160-1
from high voltage damage on the USB/wall adapter inputs
with an external N-channel MOSFET and a resistor.
The LTC4160/LTC4160-1 are available in a 3mm × 4mm
× 0.75mm QFN surface mount package.
