The is a quad Protector Switch that placed in series with the signal path and protects sensitive components from overvoltage faults in that path. The channel protector prevents over voltages when powered and unpowered and it is ideal for use in applications where correct power supply sequencing cannot always be guaranteed. The primary supply voltages define the on-resistance profile, while the secondary supply voltages define the voltage level at which the overvoltage protection engages. When no power supplies are present, the channel remains in the off condition and the channel inputs are high impedance. Under normal operating conditions, if the analog input signal levels on any Sx pin exceed positive fault voltage POSFV or negative fault voltage NEGFV by a threshold voltage VT, the channel turns off and that Sx pin becomes high impedance. If the DR pin is driven low, the drain pin Dx is pulled to the secondary supply voltage that was exceeded.
