UCD3138A: Max power consumption

Gokul K

Part Number: UCD3138A

I need to find the total supply current of the part UCD3138ARGCR.

And also the absolute maximum power the controller will consume (when everything is enabled and max power is used).

Please support.

Thanks.

Total current is 90mA, so the power consumption is less than 300mW.

The data sheet says the max is 105mA:

105mA is taken when every peripheral runs at the fastest speed. At normal operation, it is not.

From the OP:

"And also the absolute maximum power the controller will consume (when everything is enabled and max power is used)."

He also did not give a temperature range, so I guess we have to assume the max.

It is fine. it won't exceed 105mA.
