Dual Channel, Low Resistance Load Switch

General Description

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 RT9745A is available in the WDFN-14TL 3x2 package

with exposed pad for high power and heat dissipation.
