  DESIGN IDEAS Low Voltage PowerPath Driver
  Switches from a 3.3V or 5V
  by Peter Guan and
  Supply to Battery Backup
  Tim Skovmand
  The LTC1473L solves the problem
  of seamless power switching between
  3.3V or 5V supplies and backup battery packs (3-or 4-cell NiMH) at high
  current levels. By driving two sets of
  back-to-back N-channel MOSFET
  switches, the LTC1473L routes power
  to the input of a low voltage (3.3V to
  10V) system efficiently and inexpensively. An internal micropower boost
  regulator is included to fully enhance
  the external NMOS switches, even at
  low operating voltages. An external
  1mH inductor and 1ВµF capacitor
  charge VGG to approximately 8.5V
  above V+, providing ample drive for
  the external MOSFETs. The LTC1473L
  includes inrush-current limiting during supply switchover to produce
  smooth transitions between the DC
  supply and the battery backup and to …
