MC34VR5100A1EP I2C Logic Voltage levels

The PMIC (MC34VR5100A1EP) datasheet has logic voltage levels for I2C SDA line as Vol=0.4*VCCI2C=0.2*1.8=0.72 @Iol=2mA. This Vol=0.72V is not meeting the I2C standard voltage Vol,max=0.4V. Please confirm is this device is complaint to I2C standard?

Also VL(max)=0.2*VCCI2C=0.36V, which is very less, as per I2C standard it should have 0.3*VCCI2C, please confirm this voltage level.

 

 

If we interface this device in any I2C bus, in which any master device is sending data on SDA line with Vol,max=0.4V, then this device will not detect the input logic low voltage.

 

 

Kindly confirm the VIL,max & VOL,max levels of this PMIC IC.

 

 

Thanks

Manoj
