The LTC4412IS6#TRMPBF by Linear Technology is a Low Loss PowerPath Controller designed for efficient power switchover or load sharing. It controls an external P-channel MOSFET to create a near-ideal diode function, enabling highly efficient OR'ing of multiple power sources. This design extends battery life and minimizes self-heating.
Key features include a low quiescent current of 11µA, independent of load current. The device supports a wide supply operating range from 3V to 28V for AC/DC adapters and 2.5V to 28V for batteries. The typical voltage drop across the MOSFET when conducting is only 20mV, making it a superior alternative to Schottky diodes for power supply OR'ing.
The LTC4412IS6#TRMPBF includes an internal voltage clamp for MOSFET protection and a STAT pin that can indicate auxiliary supply connection or enable an auxiliary P-channel MOSFET. A manual control input (CTL) allows forcing the primary MOSFET off. The component is housed in a low profile, 1mm ThinSOT package, suitable for space-constrained applications.
This controller is ideal for applications such as cellular phones, notebook computers, digital cameras, USB-powered peripherals, and uninterruptible power supplies where efficient power management and automatic switching between DC sources are critical.
