I would like to Parallel the P-ch FETs in LTC4418 application for sharing the load/power dissipation. My concern is about removing back-to-back FET connection. Can it be removed and connected 3 P ch FETS in parallel? What is the purpose of connected back-to-back fets? To create a bidirectional switch? Can it be removed? How many total FEts can be paralleled? See attached LTspice model for clear understanding. If this is not the right way to connect them in parallel, could someone please show me how it needs to be done?
