USB Power Control Application with Wall Adapter Input TYPICAL APPLICATIO S LTC4055 Configured for USB Application with Wall Adapter Figure 5 shows an LTC4055 configured for USB applica- tions with the optional wall adaptor input. The program- ming 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 61.9k 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. |
