GENERAL DESCRIPTION
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 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
