MAG3110 Stop Working When After Switch Off And On

Hi all,

 

I'm using a MAG3110 on a board quite similar to the TI Sensortag, a cc2541 controlling the MAG via I2C, but without all other sensors (just the mag).

I would like to use the MAG only once in a while (say, every 10 minutes for a few seconds, to save battery), so I'm using the 20miliamp pins of the TI to control the power in and out of the MAG.

I manage to get results from the MAG up to the first shut down, after that it seems that the measurement stops. When I'm giving a continuous "1" signal through that pin I keep getting measurements.

 

What could be the problem?

 

Thank you very much in advance,

Eran
