I am sorry, but our group does not evaluate sensors nor do we use them for any applications. You could try in the processor forum where they may have used sensors.

Hi Andy, Any updates on the above topic?? We are facing the same issue in the current testing board also, since we have pulled up the A0 and A1 pins directly to 3.3V, we expect a slave address of 4B...
View ArticleForum Post: RE: TSC2007 I2C Address Configuration
Hi, Nithin, The data sheet is quite clear in the section titled, "ADDRESS BYTE" that the address pins must be tied to supply (VDD/REF on the TSC2007 ) or ground nets. Try changing your 10k resistor to...

Hi, As per the datasheet we have removed the pull up resistors and directly short the pins to Vcc (3.3V) in our current test board, but in this board also the random address mismatch is showing ( the...

Hi, Nithin, When you tied the address pins to 3.3V, is this the same 3.3V net feeding VDD/REF on the TSC2007 ? -d2
View ArticleForum Post: RE: TSC2007 I2C Address Configuration
yes the same 3.3V is connected to the A0 and A1 pins.

Hi, Nithin, So, hard tied to VDD/REF on the TSC2007 results in random behavior, but hard tied to ground works ok? On how many units have you experienced this behavior? -d2
View ArticleForum Post: RE: TSC2007 I2C Address Configuration
We have tested in 2 of our target board and found that in both of the boards the TSC2007 is showing the random behavior. The I2C lines are pulled up with a 2.2K pull up resistor to same 3.3V rail. Is...
