  Simplify Battery Charging from the USB – Design Note 320
  John Shannon
  Introduction
  The USB is fast becoming the most popular way to attach peripherals to personal computers. An important
  feature of the USB standard is that it allows for power
  transmission over the USB cable, making it possible for
  a PDA or other handheld device to charge its battery
  while it is connected to a host PC. The charger is based on the LTC4053—a standalone
  timer-terminated constant current/constant voltage
  linear charger. The LTC4053 features a thermal loop
  which maximizes the charging rate under all conditions by regulating the maximum die temperature. Less
  sophisticated linear chargers must run lower charging
  rates or risk overheating, thus increasing charge times. The USB specification defines load current limits that
  USB peripherals can draw from the USB. Three operating modes are allowed: Operation of the LTC4053 is simple. The charge current
  is set by a resistor on the PROG pin, the termination
  timer period is set by a capacitor on the timer pin and
  float voltage is preset at 4.2V. Suspend mode, where the USB peripheral draws
  less than 500ОјA from the USB cable L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks
  of Linear Technology Corporation. All other trademarks are the property of their
  respective owners. Low power mode, where the current consumption
  can be up to 100mA LTC4053

  DESIGN IDEAS Compact Solution Uses USB Power
  to Run a Device and Simultaneously
  by George Humphrey
  Charge its Battery
  Introduction
  Increasing numbers of portable devices
  are tapping into the Universal Serial
  Bus (USB) to charge their batteries.
  USB power supplied by the host allows
  batteries to be recharged at the same
  time data transfer is occurring, and in
  some cases, eliminates the need for a
  bulky wall adapter. The challenge is
  to provide battery charging and device
  operation simultaneously in the most
  efficient manner, while not exceeding
  either 100mA or 500mA as required
  by the USB specification. 100mA 500mA
