Power Multiplexer Circuit Using Common-Drain MOSFET

This power multiplexer circuit with 2 inputs and 1 output is realized on a small board. A new power multiplexer circuit usign common-drain MOSFET has been added to the already developed power multiplexer circuit reference design. These reference circuits allow switching between BBM and MBB modes by combining optimal devices such as MOSFET gate driver ICs and zener diodes from our diverse product lineup.
