LTC4412IS6 SOT-23-6 HOT-SWAP CONTROLLER ANALOG DEVICES IC

LTC4412IS6 SOT-23-6 HOT-SWAP CONTROLLER ANALOG DEVICES IC

The LTC4412IS6 controls an external P-channel MOSFET to create a near ideal diode function for power switchover or load sharing. 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. 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. Two or more LTC4412s may be interconnected to allow load sharing between multiple batteries or charging of multiple batteries from a single charger.
