  Overview of the EEPROM in LTC PSM Devices
  Nick Vergunst Introduction convenient List Of All Options Linear TechnologyВ® has a large family of devices that
  provide a great deal of power and configurability for all
  applications. These parts additionally provide onboard
  nonvolatile memory (NVM) in the form of EEPROM to
  store and recall configuration parameters and on some
  devices provide a fault log and user scratch pad. Option 1A. Manual programming with LTpowerPlayв„ў
  Built In Programming Utility (PC->NVM) These Power System Management(PSM) devices’ architectures allow them to power up and load the desired
  configuration parameters from this NVM autonomously
  with no I2C or firmware interaction required.
  A common question customers ask is, “Now that I have
  settled on a particular configuration, how do I program
  this configuration into the chip’s onboard nonvolatile
  memory (NVM).”
  Some available options are presented in rough order of
  increasing complexity throughout the document.
  NOTE: Linear Technology strongly recommends
  Option 1 for preproduction prototyping, and
  OptionВ 2, Option 3 or Option 4 for higher volume
  production. Option 5 is a convenient method to
  program a small quantity of loose ICs prior to board …

  Dual Monolithic Ideal Diode Extends Battery Run Time and
  Prioritizes Power Sources with Glitch-Free Switchover
  Joshua Yee Mobile devices increasingly
  rely on several power
  sources that must be
  interchangeable on the fly,
  such as a wall adapter and
  a backup battery, where
  switchover between sources
  must be transparent and
  immediate. The simplest
  scheme for switching
  between two power sources
  is a simple diode-OR, but
  at higher current levels,
  power losses in the diode
  are a problem. To minimize
  power losses and maximize
  battery run time, replace the
  Schottkys in a traditional
  diode-OR with the LTC4415
  dual monolithic ideal diode. IN1
