The RT9740A is a small, ultra-low RON, dual channel load switch with EN controlled pin. The product contains two N-MOSFETs that can operate between an input voltage range of 0.8V to 5.5V. Also, it supports a maximum continuous current of 6A each channel. Each switch is independently controlled by EN pins (EN1 and EN2), which can directly interface with low-voltage control signals. The RT9740A is available in the WDFN-14TL 3x2 package with exposed pad for high power and heat dissipation.
