L6470 in HiZ state chip gets hot is it normal?

Hello I am new to dSpin, but straight to the question.
I have a L6470h setup on a protoboard using schematics found in the usermanual.
But I see that the chip gets very hot even though it is in HiZ state. I measured the currency that my setup draws so I read ~26mA at HiZ, I have tried to different supply voltages 12V and 24V with both I get the same Iquiescence (but theres a difference in power consumption 0.31W and 0.62W). So as I believe the bridges are completely turned off so does almost all power go to heat? Are those current consumption values are adequate? P.S. I get these values without messing with any configurations straight after power up
