At first I am trying to detect the product version only for the device by connecting the I2C pins and VDd, VDDintf pins. but i am not able to read the register 0x48h(A0=GND) as the device is not acknowledging. When i checked the current consumption and referred the datasheet i found that the device is in standby mode(400ua) and switched to shutdown mode (40ua) by pulling the SDWNN pin to ground. But i am not able to get the chip into the active mode. I am not able to find any information on the application note or the datasheet. please assist me to test the I2c communication of the TDA8026 device.</P><P><BR />Thanks and Regards<BR />pyt</P> Thu, 18 May 2023 06:30:14 GMT pyt351 2023-05-18T06:30:14Z https://community.nxp.com/t5/Other-NXP-Products/TDA8026-active-mode/m-p/1652826#M17789 <P>Hi&nbsp;@Community<BR /><BR />I'm trying to interface the TDA8026 CAKE Daughter board with host controller.
