Dear Sir
I want to know how to select pull-up resistor of I2C in TSC2007, my power supply is 3.3V
I use TSC2007 in my project, when I use 1.2K or 4.7K as pull-up resistor of I2C, my host MCU can not receive any ACK from TSC2007, if I use 2.2k resistor, my host can receive the ACK signal and communicate well. Can you tell me the reason and how to select the pull-up resistor for SDA &SCL?
Thank you in advance.
