MC4x DOUT HS or PWM HS Over current threshold

What is the current level that triggers over current diagnostics when HS outputs are used in parallel?

+1

Overload threshold is > 4200 mA for the MC4x Digital out HS. 

This is measured on the individual pin. Thus, if you have it perfectly balanced, two outputs in parallel could drive the double current without triggering this error detection. 


In PWM mode, overload detection is not based on current measurement. 

Do note that for continuous operation, there is a max load limitation.

Both DOUT and PWM have protection against over-temperature.
