ADG467BR is a three port device that combines a bidirectional dual TVS diode and a quad SPST switch in one package for low voltage circuit protection and switching applications. The ADG467BR can be used as a circuit breaker, signal isolator, level shifter or signal translator. It is featured with a -2V nominal breakdown voltage, small package size, relatively low off-state leakage current, and its switching capability of up to 27V DC and up to 30A in pulsed conditions.

Application Fields of ADG467BR

ADG467BR is suitable for various applications, including automotive, communications, industrial control, medical instrumentation, tools, and consumer electronics. With its circuit protection feature, the ADG467BR provides protection for both over-voltage and under-voltage conditions in these application fields. Its low on-resistance switch can be used in switching applications in these fields, to provide signal translation, or for power distribution.

Working Principle

ADG467BR utilizes a dual TVS diode array to provide ESD protection and a quad SPST switch array for signal switching. The dual TVS diode array provides robust protection during both over-voltage and under-voltage conditions. The TVS diodes have a breakdown voltage of -2V nominal and a clamping voltage of -6V maximum, which can redirect fault current away from the system quickly and minimize the damage to the system. The quad SPST switch array provides low on-resistance switching capability for signal translation, level shifting, signal isolation, and power distribution.

The ADG467BR is designed to operate in a wide range of temperatures, from -40℃ up to 150℃. It is also featured with a wide range of leakage currents, from 10nA to 5µA in its off-state, making it suitable for low power applications.

Conclusion

ADG467BR is a three port device that combines a bidirectional dual TVS diode and a quad SPST switch in one package, making it suitable for many applications such as automotive, communications, industrial control, medical instrumentation, tools, and consumer electronics. It provides robust circuit protection in both over-voltage and under-voltage conditions, while also providing low on-resistance switching capability for signal translation, level shifting, signal isolation, and power distribution.
