RT9745A

Dual Channel, Low Resistance Load Switch

General Description

Features

^Integrated Dual Channel Load Switch

^Input Voltage Range : 0.8V to 5.5V

^Low R_ONResistance

The RT9745Ais a small, low R_ON, 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 6Aeach channel. Each switch is independently

controlled by EN pins (EN1 and EN2), which can directly

interface with low-voltage control signals.

^R_ON= 27mΩ at V_IN= 5V (V_DD= 5V)

^R_ON= 27mΩ at V_IN= 3.6V (V_DD= 5V)

^R_ON= 27mΩ at V_IN= 1.8V (V_DD= 5V)

^6A Maximum Continuous Switch Current Per

Channel

The RT9745Ais available in the WDFN-14TL3x2 package

with exposed pad for high power and heat dissipation.

^Low Quiescent Current

^75μA (Both Channels)

^55μA (Single Channel)

^Low Control Input Threshold Enables Use of 1.4V/

1.8V/2.5V/3.3V Logics
