LTC4416IMS#PBF

LINEAR TECHNOLOGY  LTC4416IMS#PBF  芯片, PFET控制器, 理想二极管, 36V, 8MSOP

The is a near Ideal Diode 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. The LTC4416 integrates two interconnected PowerPathTM 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. The device also contain a "fast-on" feature that dramatically increases gate drive current when the forward input voltage exceeds 25mV. The LTC4416 "fast off" feature is engaged when the sense voltage exceeds the input voltage by 25mV. The wide operating supply range supports operation from one to eight Li-Ion cells in series.
