Typical Application
Description
The LTC®1710 SMBus dual switch has two built-in 0.4Ohms/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 5.5V while maintaining the SMBus specified 0.6V VIL and 1.4V VIH input thresholds. Using the 2-wire interface, CLK and DATA, the LTC1710 follows SMBus’s Send Byte Protocol to independently control the two 0.4Ohms 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.MS-8,SO-8
