TYPICAL APPLICATIONS
LTC4055/LTC4055-1 Congured for USB Application
with Wall Adapter
Figure 5 shows an LTC4055/LTC4055-1 congured for
USB applications with the optional wall adapter input. The
programming resistor (RCLPROG) is set to 105k which sets
up a nominal current limit of 467mA in high power mode
(92mA in low power). This is done to prevent the various
tolerances in the part and programming resistors from
allowing the input current supplied by VBUS to exceed the
500mA/100mA limits.
The programming resistor (RPROG) with a value of 60.4k
sets up a nominal charge current of approximately 800mA.
Note that this is the charge current when the wall adapter
is present. When the wall adapter is absent, the current
limit supersedes the charge current programming and
charge current is limited to 467mA.
