Dear All,
请问这款芯片的i2c接口上的,sdai和sdao 可以接在一起,直接与我主控CPU的 i2c sda引脚相连吗?
如果不可以,请问该如何接才能兼容通用的i2c接口啊
谢谢
SDAI: Serial data input for I2C bus. Requires an external pull-up resistor to VDD. This pin can be connected to SDAO for non-isolated systems. See Figure 50.
SDAO: Open-drain I2C bus output data line. Requires an external resistive pull up. The TPS23861 uses separate SDAO and SDAI lines to allow optoisolated I2C interface. SDAO can be connected to SDAI for non-isolated systems
