The is a near Ideal Diode for power switchover. 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 20mV. Two or more LTC4414s may be interconnected to allow switchover between multiple batteries or charging of multiple batteries from a single charger. The wide supply operating range supports operation from one to eight Li-Ion cells in series. The gate driver includes an internal voltage clamp for MOSFET protection. The STAT pin can be used to enable an auxiliary P-channel MOSFET power switch when an auxiliary supply is detected. This pin may also be used to indicate to a microcontroller that an auxiliary supply is connected. The control CTL input enables the user to force the primary MOSFET off and the STAT pin low.
