Standby current consumption?

Postby MikeB » Mon Aug 06, 2007 11:49 am

Hi,

Could you tell me what the current consumption of the DSATX is when the PC has been put into Sleep mode with 5VSB programmed to be left on and ACC low? I know that the overall current consumption depends on what the motherboard draws from 5VSB; I just want to know what the DSATX draws in this mode, so I can work out what the battery drain will be in Sleep with my car PC.

Many thanks,

Mike.

At 12 volts in it is about 40mA.

That runs the micro-controller and the +5VSB rail with no load.

In full sleep mode it is ~3mA

Jeff,

Thanks. What I'd really like is a much lower consumption in this state to help make Sleep mode a practical proposition. At 40mA, I think that the PSU would be responsible for about half the total current drain on the battery for my system in sleep and it would be very nice to be able to eliminate most of this.

Mike.

No, you do not need an brainstem. I used for my DSATX a Phone Datacable. Connected to the DSATX (virtual COM-Port) and it works just fine! :)

The Brainstem is very bugy for me.
