General Description
The Adapter Interface Circuit (AIC) is used to sense the presence of an external power source for a portable
computer. 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
switchover circuit. This significantly decreases additional heat dissipation during simultaneous fast battery
charging while running a computer, particularly in Maximum Performance mode of operation
Features
q
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
q
Allows the implementation of intelligent switchover circuits for portable systems
q
LM2601 shuts down automatically when adapter is removed
q
Low leakage current from battery when not powered
q
Drives P-channel FETs, no Schottky diodes are required
q
No reverse inrush current from battery into the adapter output capacitance
q
