I believe you are asking about requiring a host controller with the LTC4291 and auto mode operation. For the LTC4291, a code download must be performed at every power cycle. After firmware download, the LTC4291/LTC4292 chipset may be run autonomously without any further host control by setting the AUTO pin high and a hardware reset with the RESET# pin. If a power cycle occurs, the firmware must be downloaded again.
Moving forward, the LTC4291-1 is recommended for all new designs.
