LTC4416IMS#PBF

LTC4416 is a low loss, dual channel, power path controller for large PFET's. 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. When conducting, the voltage drop across the MOSFET is typically 25mV. This device 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 application 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.
