The LTC
300mA switches that are controlled by a 2-wire SMBus
interface. With a low standby current of 14 A (3.3V), the
LTC1710 operates over an input voltage range of 2.7V to
5.5V while maintaining the SMBus specified 0.6V V
1.4V V
Using the 2-wire interface, CLK and DATA, the LTC1710
follows SMBus’s Send Byte Protocol to independently
control the two 0.4 internal N-channel power switches,
which are fully enhanced by onboard charge pumps.
The LTC1710 has one three-state programmable
address pin that allows three different addresses for a total
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.
