LTC4416/LTC4416-1 Dual PowerPath™ Controllers Analog Devices LTC4416/LTC4416-1 Low Loss Dual PowerPath™ Controllers control two sets of external P-channel MOSFETs to create two near-ideal diode functions for power switchover circuits. This feature 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. 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.
