Hi, a customer is validating teh use of WL1837MOD in a thermal constraint environnment.
So knowledge of the Power dissipation is important : thanks to clarify the values that can be used for his modeling .
Using Ref Manual :
- It says for 1.8V (IOs) it is 200 mA , so it is = 1.8*0.2 = 0.36W
- For Vbat it is 3.3V, from the datasheet it says.
For Transmission, at worst case it is 510mA, which is = 3.3*0.51 = 1.68W.
So, if we leave the caliberation, so the total power is = 1.68+0.36 = 2.04W. - what is the thermal disspation of the module ?
For Bluetooh, as per the datasheet, it is 50mA, = 3.3*0.05 = 0.165W
So, as we have Wifi+BT will be used simultaneously, what we should consider
Is it : Wifi+BT = 2.04W (Internal switching)
Or Wifi +BT = 2.04+0.165 = 2.205Watts.
Please let us know, what we need to consider, for power estimation and power dissipation and this is very much needed for our project
Thanks
Nicolas
