• TEF8102 1.1V_FS不上电

    使用FS8430芯片的BULK2输出1.8V,使用TPS7A8101-Q1将1.8V换换成1.1V作为TEF8102的1.1V_FS电源,TEF8102的1.1V和1.8V供电参考验证版设计,使用PHPT60603NY,集电极采用2.3V供电,2.3V使用FS8430的BULK3产生。TEF8102的3.3V使用FS8430的LDO1产生。目前1.1V、1.8V、2.3V和3.3V都正常,FS8430的BULK2输出的1.8V也正...

  • PCA9698使用前咨询

    我有个产品想用PCA9698DGG这个芯片扩展IO,只做输出使用,我想请问: 1、由于我MCU引脚有限,只有三根引脚用于扩展,我想接SDA、SCL和RESET,因为只做输出使用,请问OE输出使能引脚可以直接接低电平吗? 2、因为只做输出使用,INT引脚可以不接吗? 3、我扩展IO的目的是模拟多路SPI接口,请问这个芯片的响应速度是否可以满足?(我使用的SPI速度不是很高)   非常感谢!
