Designed to operate from 1.65 to 4.5 V, this device is ideal for portable applications. It offers low ON resistance (0.6 Ω) at VCC = 4.5 V ( typical TA = 25 ºC). The SEL input threshold is compatible to 1.8 V, and provides control to the switches. Table 1. The switch S1 is ON (connected to common port D) when the SEL input is held high and OFF (high impedance state exists between the two ports) when SEL is held low. The switch S2 is ON (connected to common port D) when the SEL input is held low and OFF (high impedance state exists between the two ports) when SEL is held high. The SEL input has an integrated weak pull-down resistor to prevent SEL signal from floating. For low power consumption, the SEL input must be grounded. Power-off and over-voltage protection The STG4158 features power-off and overvoltage protection, enabling the device to be isolated during voltage fault events.

Normal operation mode 2. Isolation mode In the normal operation mode, the switch functions as a normal SPDT, with the SEL pin that selects the switch to be either ON or OFF. Either S1 or S2 is connected to common channel D. In the isolation mode, all the switches are OFF. S1 or S2 are isolated from common channel D. The S1, S2, D ports have a 1 MΩ impedence to ground. The operation modes are made possible by special detection circuitry that detects the voltage level at D, S1 and S2 supplies. Depending on these voltage levels, the device goes into isolation mode or normal operation mode accordingly. The isolation mode is a feature of the device that is useful during fault conditions that occur in the application environment. Table 9.
