Hi David,

Different product may have it’s own operational temperature class.
Please refer to PTS (table 7-1) for the product you concerned.

For example, 4114634 MC7304 PTS, section “Power state transitions” mentioned the trigger level (Table 5-5) and voltage/temperature monitoring state machines (Fig 5-1).

By default, it will enters low power mode with over HI CRIT (or lower LO-CRIT) temperature.

Hope it helps.
Thx

sorry - I didn’t say what I’m using
MC8790V

and I don’t find any data sheet of it - maybe you can help me with this?
so I will know what every trigger level mean

Thanks ,

Hi David,

Here’s the link to PTS for MC8790V:
http://developer.sierrawireless.com/Resources/Resources/AirPrime/Minicard/2111280_AirPrime_MC8790V_with_Audio_PCI_Express_Mini_Card.aspx

But that PTS does not cover the power state transitions mentioned, could you please refer to new products’ PTS as reference?
For example: http://developer.sierrawireless.com/Resources/Resources/AirPrime/Minicard/2400089_AirPrime_MC7710_Product_TechSpecs.aspx
I think the idea is just the same.

Hope it helps.
Thx.
