Figure 8.4 USB Battery Charging Detection (3 - pin)
To calculate the equivalent resistance on the LTC4053 PROG pin select a charge current, then Res =
1500V/I
For more configuration options of the LTC4053 refer to:
AN_175_Battery Charging Over USB
Note: If the FT201X is connected to a standard host port such that the device is enumerated the battery
charge detection signal is inactive as the device will not be in suspend.
