application information STG4158 10/ 4 application information power-off and over-voltage protection the STG4158 has two operation modes: 1. 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 port s have a 1 m ? 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 th at is useful during faul t conditions that occur in the application environment. table 9. voltage conditions v cc v d,s (voltage at common port d, s1 or s2) voltage condition mode floating 0 ? 4.5 v all switches off s1,s2 and d are isolated from each other isolation 0?0.5v 0?4.5v all switches off s1, s2, d are isolated from each other isolation v cc >0.5 v d,s >v cc + 0.4 all switches off s1,s2 and d are isolated from each other isolation 1.65 ? 4.5 v 0?v cc either s1 or s2 is connected to d, depending on sel input normal
