4通道电平变换I²；C总线/SMBus转发器

PCA9519 正常供应

PCA9519是一款4通道电平变换I²C总线/SMBus转发器，能使处理器低电压2线串行总线连接标准I²C总线或SMBus I/O。在电平切换过程中保留I²C总线系统所有工作模式和功能的同时，它还允许通过为数据(SDA)和时钟(SCL)线路提供双向缓冲来扩展I²C总线，从而使I2C总线或SMBus在高电压侧的最大电容达到400 pF。SDA和SCL引脚为耐过压且在PCA9519未通电时为高阻抗。

端口B驱动器兼容SMBus I/O电平，而端口A使用电流感应机制检测输入或输出低电平信号，以防止总线锁定。端口A使用1 mA上拉电流源和200 Ω下拉驱动器。这使端口A上的低电平适应更小的电压摆幅。端口A内部缓冲器上的输出下拉低电平设为大约0.2 V，而内部缓冲器的输入阈值设为比输出电压低电平的低大约50 mV。当端口A I/O内部驱动为低电平时，输入端不会将低电平识别为低电平。这能防止发生锁定状况。端口B上的输出下拉驱动真正的低电平且输入电平设为大约SMBus或I²C总线电压电平的0.3，能使端口B连接至任何其他I²C总线器件或缓冲器。

除非VCC(A)高于0.8 V且VCC(B)高于2.5 V，否则不会启用PCA9519驱动器。也可使用使能(EN)引脚在系统控制下打开和关闭驱动器。应该注意，当总线闲置时仅改变EN引脚的状态。
