Controller IC Chip - MAX8725ETI MAX8725E MAX8725 8725E chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0679)

The  MAX1909/MAX8725  highly  integrated  control  ICssimplify  construction  of  accurate  and  efficient  multi-chemistry  battery  chargers.  The  MAX1909/MAX8725use  analog  inputs  to  control  charge  current  and  volt-age, and can be programmed by a host microcontroller(μC)  or  hardwired.  High  efficiency  is  achieved  throughuse of buck topology with synchronous rectification.The 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.  The  MAX1909/MAX8725  provide  a  digital  outputthat  indicates  the  presence  of  an  AC  adapter,  and  ananalog  output  that  monitors  the  current  drawn  from  theAC  adapter.  Based  on  the  presence  or  absence  of  theAC adapter, the MAX1909/MAX8725 automatically selectthe  appropriate  source  for  supplying  power  to  the  sys-tem  by  controlling  two  external  p-channel  MOSFETs.Under  system  control,  the  MAX1909/MAX8725  allow  thebattery  to  undergo  a  relearning  or  conditioning  cycle  inwhich  the  battery  is  completely  discharged  through  thesystem load and then recharged.The  MAX1909  includes  a  conditioning  charge  featurewhile  the  MAX8725  does  not.  The  MAX1909/MAX8725are  available  in  space-saving  28-pin,  5mm  ✕5mm  thinQFN packages and operate over the extended -40°C to+85°C  temperature  range.  The  MAX1909/MAX8725  arenow available in lead-free packages.

Please make sure you have advanced soldering skill to solder the chips that you will order from us. When you receive before using it, please confirm the chip you received is brand new as described,if you suspect the chip is not new or not as described. Please don't use it and contact us immediately. Once it has been used, no return will be accepted. Please check before you buy it.Thanks for your understanding.

Lead solder balls' melting point is 180?, 210?-215? is the best melting temperature.
Lead Free solder balls' melting point is 217?, 235?-245? is the best melting temperature.

The temperatures listed above are the chip's solder balls actual temperatures (they are measured by the measuring wire on theBGA machine),but not the temperatures from the BGA rework station's top bottom heat guns.

If soldering a new Lead solder balls chip with Lead Free temperature curve (profile), it will overheat the new chip.
If soldering a new Lead Free solder balls chip with Lead temperature curve (profile), it will not completely melt the lead free solder balls on the new chip.

Most of the laser head have one or twoanti-static pointto prevent static burn laser tube as a security measure. It's better to wear an antistatic wrist strap or wash your hands before welding and installation.

When using a high-grade anti-static soldering iron,you can remove the anti-static point directly, ordinary iron requires special attention, heat iron to reached soldering temperature,then remember to turn off the iron's power, prevent static of iron burn laser tube
