CIRCUIT INFORMATION Figure 21 shows a simplified schematic of a channel protector circuit. The circuit is made up of four MOS transistors—two NMOS and two PMOS. One of the PMOS devices does not lie directly in the signal path but ...
Page 10
ADG467 When a negative overvoltage is applied to the channel protector circuit, the PMOS transistor enters a saturated mode of operation as the drain voltage exceeds V − V (see Figure 24 the SS TP case of the ...
Page 11
TRENCH ISOLATION The MOS devices that make up the channel protector are isolated from each other by an oxide layer (trench) (see Figure 26). When the NMOS and PMOS devices are not electrically isolated from each other, parasitic junctions between ...

ADG467 APPLICATIONS INFORMATION OVERVOLTAGE AND POWER SUPPLY SEQUENCING PROTECTION The ADG467 is ideal for use in applications where input overvol- tage protection is required and correct power supply sequencing cannot always be guaranteed. The overvoltage protection ensures that the output ...

... CMOS devices when the power supplies are off. The ideal solution is to use a channel protector in conjunction with a TVS to provide the optimal leakage current specification and circuit protection. Figure 28 shows an input protection scheme that uses both a TVS and a channel protector. The TVS is selected with a reverse ...
