Allowable power for digital input pull-up


HRK

Recommended Posts

Hi,all

I want to light the LED when the switch is turned on

(for launch control and flat shift)

The digital input is set to pull-up (12+), and the LED is going to be installed between the switch connected to GND.
Is there a problem with power consumption?

LED power consumption is 2.2V 20mA
I'm going to drop the current with a current regulatve diode.

 

Thanks.
