描述
描述 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 V IL and 1.4V V IH 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.
