LTC1710

SMBus Dual Monolithic

High Side Switch

FEATURES

DESCRIPTION

The LTC^®1710 SMBus dual switch has two built-in 0.4Ω/

300mA switches that are controlled by a 2-wire SMBus

interface. With a low standby current of 14µA (3.3V), the

LTC1710 operates over an input voltage range of 2.7V to

5.5Vwhile maintainingthe SMBus specified0.6V V_ILand

1.4V V_IHinput thresholds.

■

Two 0.4

Ω/300mA N-Channel Switches

■

Available in MS8 and SO-8 Packages

SMBus and I²C Compatible

0.6V V_ILand 1.4V V_IHfor DATA and CLK

Low Standby Current: 14µA

Separate Drain Connection to SW0

Three Addresses from One Three-State Address Pin

Independent Control of Up to Six Switches

Built-In Power-On Reset Timer

Using the 2-wire interface, CLK and DATA, the LTC1710

follows SMBus’s Send Byte Protocol to independently

control the two 0.4Ω internal N-channel power switches,

which are fully enhanced by onboard charge pumps.

Built-In Undervoltage Lockout

The LTC1710 has one three-state programmable

addresspinthatallowsthreedifferentaddressesforatotal

of six available switches on the same bus. The LTC1710

also features a separate user-controlled drain supply

(SW0D) to Switch 0 so that it can be used to control

SMBus peripherials using a different power supply.
