LTC4412

Low Loss PowerPath^TM

Controller in ThinSOT

FEATURES

DESCRIPTIO

The LTC^®4412 controls an external P-channel MOSFET to

create a near ideal diode function for power switchover or

load sharing. This permits highly efficient OR’ing of mul-

tiple power sources for extended battery life and low self-

heating. When conducting, the voltage drop across the

MOSFET is typically 20mV. For applications with a wall

adapter or other auxiliary power source, the load is auto-

maticallydisconnectedfromthebatterywhentheauxiliary

source is connected. Two or more LTC4412s may be

interconnected to allow load sharing between multiple

batteries or charging of multiple batteries from a single

charger.

■

Manual Control Input

The wide supply operating range supports operation from

one to six Li-Ion cells in series. The low quiescent current

(11μA typical) is independent of the load current. The gate

driver includes an internal voltage clamp for MOSFET

protection.

APPLICATIO S

■

Cellular Phones

The STAT pin can be used to enable an auxiliary P-channel

MOSFET power switch when an auxiliary supply is

detected. This pin may also be used to indicate to a

microcontroller that an auxiliary supply is connected. The

control (CTL) input enables the user to force the primary

MOSFET off and the STAT pin low.
