LM2601
Adapter Interface Circuit
General Description
The Adapter Interface Circuit (AIC) is used to sense the
presence of an external power source for a portable com-
puter. It notifies the computer if a source is present and
indicates if the source is appropriate for charging battery
packs inside the computer. The AIC also senses an adapter
current and its direction. AIC isolates the adapter and signals
the computer when peak current threshold is exceeded.
LM2601 drives P-channel FETs. No high current rated
Schottky diode is required to implement an adapter switcho-
ver circuit. This significantly decreases additional heat dissi-
pation during simultaneous fast battery charging while run-
ning a computer, particularly in Maximum Performance
mode of operation
Features
n
Detects an AC-DC adapter suitable for battery charging
or an airplane or car power line adapter that should not
be used for battery charging
n
Allows the implementation of intelligent switchover
circuits for portable systems
n
LM2601 shuts down automatically when adapter is
removed
n
Low leakage current from battery when not powered
n
Drives P-channel FETs, no Schottky diodes are required
n
No reverse inrush current from battery into the adapter
output capacitance
n
Allows for battery capacity gas-gauge calibration under
system software/firmware control
n
Adapter over current threshold programmable with
external resistors
n
Wide input range: 5V - 24V
n
Available in TSSOP-14 package
Applications
n
Portable Computers
n
Portable IAs (Internet Appliances, Information
Appliances)
n
Other Battery Powered Devices
