Source selector for dual-input power rails
The LTC4415EDHC#PBF is a dual-input source selector switch from the Analog Devices PowerPath series, designed to autonomously switch between two power sources — typically a main supply and a backup battery — and deliver up to 4 A continuous to the load. With a 2:2 input-to-output ratio, it handles two independent power paths internally, each controlled by a P-Channel MOSFET, so the load sees a seamless transition without a break in supply.
4 A continuous with 44 µA overhead
Rated for 4 A maximum output per channel, the LTC4415 handles the current draw of a small processor module or a sensor node's power rail — enough to power a Cortex-M4 class MCU plus its peripherals without a separate load switch.
Active production, ROHS3 compliant
The part is ROHS3 compliant, meeting the latest EU directive on restricted substances — no exemption declarations needed for the BOM.
