Part Number:UCD90160
Hello TI Tech support.
We are having issue with the UCD90160. It seems like the Bias current is off while the device is reading the voltage at Addr0 and Addr1 to set the I2C address. We remove the decvice from the system and put it on an IC tester to measure the Bias current. The spec said it shall bias 10uA, Is it just for addr0 only, or both addr0 and addr1. When is the device supply the bias current. I connect a 41.2k ohm resistor from addr[0:1] to ground and measure the voltage at addr[0:1] and got 0V. Where if I go wrong. Please advise.
Thank you in advance.
