Figure 7.6 USB Battery Charging Detection (3 pin)
To calculate the equivalent resistance on the PROG pin select a charge current, then Res = 1500V/I_chg
For more configuration options of the LTC4053 refer to:
AN_175_Battery Charging Over USB
Note: If the FT230X 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.
