LTC4416EMS#TRPBF

LTC4416 is a 36V, low loss dual powerpath controller for large PFETs. It control two sets of external P-channel MOSFETs to create two near ideal diode functions for power switchover circuits. This permits highly efficient OR’ing of multiple power sources for extended battery life and low self heating. For applications with a wall adapter or other auxiliary power source, the load is automatically disconnected from the battery when the auxiliary source is connected. It integrates two interconnected PowerPath™ controllers with soft switchover control. The “soft-off” switchover permits the users to transfer between two dissimilar voltages without excessive voltage undershoot (or VDROOP) in the output supply. It is widely used in applications such as high current powerpath switch, industrial and automotive applications, uninterruptible power supplies, logic controlled power switch, battery backup system, emergency systems with battery backups etc.
