Q 

What happens to the output during an over-voltage event?

A 

The drain output will be clamped during an overvoltage fault condition. The
ADG5248F, ADG5249F, and ADG5243F have secondary supplies (POSFV, NEGFV) which
will be the clamp voltages on those…

Q 

Are these parts pin-pin compatible with existing parts?

A 

Yes, the ADG5208F/ADG5209F are pin-for-pin compatible with the ADG5208/ADG5209
and ADG1208/ADG1209. They are drop in replacements if overvoltage protection is
required. However, they are…

Q 

What are the system benefits of fault diagnostics?

A 

For systems that are sensitive during a start-up sequence, the active low
operation of the fault flags allow the system to ensure that the ADG5248F is
powered on and that all input voltages are…

Q1. What are the key benefits of these fault protected switches?

A1.  There are a number of key features on these parts

• Overvoltage fault protection to +/-55V levels in powered and unpowered state
• Secondary supply rails to allow for user defined fault…
