PCA9511A
正常供应

PCA9511A是一款热插拔I²C总线和SMBus缓冲器，允许将I/O卡插入带电背板中而不会损坏数据和时钟总线。控制电路会防止背板连接到卡上，直至背板上出现停止命令或总线闲置且卡上没有总线冲突。当连接建立时，PCA9511A提供双向缓冲，保持背板和卡电容隔离。

PCA9511A上升时间加速器电路允许使用更弱的DC上拉电流，同时仍满足上升时间要求。PCA9511A采用数字使能输入引脚(在输入高电平时启用器件并在输入低电平时强制器件进入低电流模式)，和开漏READY输出引脚(指示背板和卡侧是(高电平)或否(低电平)连接在一起)。

插入过程中，PCA9511A的SDA和SCL线路预充电至1V，以最大程度地减少芯片寄生电容充电所需的电流。

  • 兼容I²C总线标准模式、I²C总线快速模式和SMBus标准
  • 所有SDA和SCL线路(阈值为0.6V)上的内置ΔV/Δt上升时间加速器需要相同的总线上拉电压和供电电压(VCC)。
  • 高电平有效的使能输入
  • 高电平有效的READY开漏输出
  • VCC=0V时SDA和SCL引脚为高阻抗
  • 所有SDA和SCL线路上有1V预充电

This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode.
