DRV8251A: DRV8251ADDAR

Tool/software:

Hi Sir,

we are facing IN1 and IN2 input signals.

Initially we are giving IN1 and IN2 as High (3.3V), and we are giving IN1 or IN2 as low (0.0V) from MCU based on Motor forward or reverse direction requirement.

Problem we are facing is IN1 or IN2 is getting down only 1.6V instead of 0.0V. 

MCU GPIO pins is directly connected to IN1 and IN2 through connector's from MCU (male connector) and H-Bridge (female connector) board. We have not used any series resistor between MCU GPIO pins and IN1/IN2, we also not used any resistor between IN1/IN2 to GND (or) MCU GPIO pins to GND.

Could any one guide us to resolve this problem or if required any installation in DRV8251A IC.
