Product Number: ADG1636

Hi,

I am Designing a PCB of power management unit for a RADAR system . I want to sequence +5,+3.3,-5 and -3.3V voltage rails. I was looking for a load switch that can control supply of +5V,-5V, +3.3V and -3.3V. I was wondering if there were any load switches that can be used to control the turn on/off of both the negative and positive supplies, since a cursory look at the available load switches doesn't show me any that would work. If not, are there any alternative solutions you can recommend?

Thanks,

Hi Rabia ,

Let me dive into the details and get back to you with some fantastic updates but before that could you show me a block diagram of what you want to do in your testing so I can get a clear view ?

Thanks.

you can see connection of load switches in this diagram. Current flowing thru each rail is less than 2A.

What is the maximum current that a pin can deliver?

Hi Rabia ,

It might be beneficial to explore the power group which may suitable for your application. Moreover, considering the nature of your application, I would recommend shifting your focus towards the power group, as the precision MEMs could potentially be more than what is required.
