Hello,


I have a question regarding the LTC4412.


I was wondering if it is possible to wire the IC as per figure 4 from the datasheet, but control the CTL pin simply via one of the supply voltages so that the MCU is not needed.

My circuit will mainly be powered by a 2-3 cell lipo but I would like to switch over to USB (disconnect the battery) when the cable is plugged in.
