Controller IC Chip - Mofset MAXIM MAX1772EEI MAX1772 chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0644) Low-Cost, Multichemistry Battery-Charger Building Block The  MAX1772  is  a  highly-integrated,  multichemistrybattery-charger  control  IC  that  simplifies  the  construc-tion  of  accurate  and  efficient  chargers.  The  MAX1772uses  analog  inputs  to  control  charge  current  and  volt-age and can be programmed by the host or hardwired.High  efficiency  is  achieved  by  a  buck  topology  withsynchronous rectification. Maximum  current  drawn  from  the  AC  adapter  is  pro-grammable  to  avoid  overloading  the  AC  adapter  whensupplying  the  load  and  the  battery  charger  simultane-ously.  This  enables  the  user  to  reduce  the  cost  of  theAC  adapter.  The  MAX1772  provides  outputs  that  canbe  used  to  monitor  the  current  drawn  from  the  ACadapter, battery-charging current, and the presence ofan AC adapter. The  MAX1772  can  charg
