open drain configuration. However, only pseudo open drain configuration is for KLx3family. What is "pseudo open drain"? Does that mean that the SDA behaves as open drain, but SCL is still driven push-pull? Is there any way to achieve true open drain operation for...
尝试解决1:加上拉电阻 如果只是100uA的逻辑输出能力,这里就基本可以看成是open-drain输出结构了(相对Darlington管的驱动需求来说)。所以我在GPIO上加了个1K的上拉电阻,实测电压2.8V,驱动逻辑完全正常了。(可以大概计算管子需求的电流在600uA左右) 但是,设计之初默认是所有relay都不开启,加上拉之后就变成了所有relay...
Just want to confirm with you if LP8866S-Q1 I2C pins OD or push-pull? Customer need this info for an issue shooting in system. Thanks. Johnny 2 年多前 +1Zhiqian Wu2 年多前 TI__Mastermind22695points Hi, Johnny SDA pin is open-drain. SCL is an input pin...

The I2C bus controller output can be push-pull or open-drain (pullup resistors may be required) and the I2C bus device output can be open-drain (pullup resistors are required to pull the SCL2 and SDA2 outputs to VDPU). However, if either output is push-pull, data must be ...
