MP6513GJ,unexpected output condition

Motor Drivers/Sensors

Hi, I have MP6513GJ ,it work at 12Vdc.The range for input pins is 0-3.3VDC. I noted in some cases,statically, i have IN1 at 0V, IN2 at 0V and at same time i have OUT 1 to GND and OUT 2 at +12V,then the coil output is powered…I thik with Inputs both at 0 V , i must to have OUT1 and OUT2 at high impedance… Where is my error? Thanks in advance…

Hello,

The Input range for the MP6513 is 2.5V to 21V. It would also help further narrow down this issue if you had a schematic to show here?

Let me know.

Best,
Krishan

This is simple schematic used…

I think if i have 0V in IN1 ,and 0V in IN2 ,i must don’t have output current…

Then? Now schematic is here… :wink:

If you notice this graph ( in in related datsheet) my condition is not the same as what you showed

The situation I showed in the schematic does not happen always, but occasionally after doing many switches on the inputs.
