LTC4160/LTC4160-1

Switching Power Manager

with USB On-The-Go And

Overvoltage Protection

FEATURES

DESCRIPTION

The LTC^®4160/LTC4160-1 are high efﬁciency power man-

agementandLi-Ion/PolymerbatterychargerICs.Theyeach

include a bidirectional switching PowerPath™ controller

with automatic load prioritization, a battery charger, and

an ideal diode.

Bidirectional Switching Regulator Makes Optimal

Use of Limited Power Available from USB Port and

also Provides a 5V Output for USB On-The-Go

Overvoltage Protection Guards Against Damage

180mΩ Internal Ideal Diode Plus Optional External

Ideal Diode Controller Seamlessly Provides Low

Loss PowerPath When Input Power is Limited or

Unavailable

TheLTC4160/LTC4160-1’sbidirectionalswitchingregulator

transfers nearly all of the power available from the USB

port to the load with minimal loss and heat which eases

thermalconstraintsinsmallspaces.Thesedevicesfeature

a precision input current limit for USB compatibility and

Bat-Trackoutputcontrolforefﬁcientcharging. Inaddition,

the ICs can also generate 5V at 500mA for USB On-The-

Go applications.

Instant-On Operation with Discharged Battery

Full Featured Li-Ion/Polymer Battery Charger

Bat-Track™ Adaptive Output Control For Efﬁcient

Charging

1.2A Max Input Current Limit

1.2A Max Charge Current with Thermal Limiting

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.

Battery Float Voltage: 4.2V (LTC4160), 4.1V

(LTC4160-1)

Low Battery Powered Quiescent Current (8µA)

20-pin 3mm × 4mm × 0.75mm QFN Package

The LTC4160/LTC4160-1 are available in a 3mm × 4mm

× 0.75mm QFN surface mount package.
