BD2069FJ-MGE2

Power Distribution Switches, Load Drivers Overview

The BD2069FJ-MGE2 is a dual-channel high-side power switch IC designed for USB port distribution. It operates within a supply voltage range of 2.7V to 5.5V and features an active-low control input logic. The device integrates two low on-resistance N-channel MOSFETs with a typical on-resistance of 80mΩ. It includes built-in overcurrent detection (1.5A to 3.0A), thermal shutdown, under-voltage lockout, and soft-start functions. The output turn-on time is typically 0.8ms, with a fault flag delay of 15ms. It is qualified to AEC-Q100 standards and housed in a SOP-J8 package.
