Power profiler kit maximum current (damage ??)

[Roger Clark]

I'm trying to find out if drawing more than 70mA through the PPK will damage it.

As I have a beeper on my custom board that can draw 200mA, and I'm concerned that attaching it to the PPK could damage the PPK if the code went wrong and ran the beeper.

I've taken a look at the schematic for the PPK, but its difficult to see which components the current flows through and whether 200mA would damage those components, or whether it would simply show a reading of 70mA if more than 70mA was drawn.

It should be safe to draw up to 400mA on the external connector. The bottle neck are the resistor switches (ADG801).

Thanks.

Thats a relief
