DRV8210EVM: The input current of EN/IN1 is 3.44mA average

Thank you. I was successful to limit the current.  However, when I limited the current, the OUTx of drv8210evm cannot output voltage 

Hello,

3.44mA of current into an input logic pin is way too high.  Have you tried multiple devices?  Is this on your own board or EVM?  Per spec, current into pin should be 50uA max with input "high" condition.

I have used arduino uno and nrf5340 to input the high level logic signal. Both of them measured the high current which is over 50uA.

Best,

Thomas

Thomas,

Have you tried more than one IC?  Either their is a measurement error or the device is broken.

I have tried to use arduino uno and nrf5340 to control motor through tps22916evm(which is a kind of switchhttps://www.ti.com.cn/tool/cn/TPS22916EVM?keyMatch=&tisearch=search-everything&usecase=hardware). When I used  arduino uno or nrf5340 to give tps22916evm the high level logic signal, both of them could successfully drive motor without any heavy current input.

Thomas,

So everything is normal now?  I am confused on the question at this point.

Ryan,

I could successfully limit the current, but when the current is limited, the OUTx of drv8210evm still cannot output voltage

Jacob,

I think this is not the solution to me because the way it mentioned is to add a resister. However, this resister will make the input voltage drop which makes the input signal be high level to the INx pin. And also, I think that R2, R3, R4 are pull-down resister for the initial state of INx pins are low level. Do you have any idea?
