PCA9510 - Hot swappable I2C and SMBus bus buffer

Datasheet Summary

Description

The PCA9510 and PCA9511 are hot swappable I2C and SMBus buffers that allows I/O card insertion into a live backplane without corrupting the data and clock buses.

Features

  • Bi-directional buffer for SDA and SCL lines increases fanout and prevents SDA and SCL corruption during live board insertion and removal from multi-point backplane systems.
  • Compatible with I2C standard mode, I2C fast mode, and SMBus standards.
  • ∆V/∆t rise time accelerators on all SDA and SCL lines (PCA9511 only).
  • Rise time accelerator threshold of 0.6 V.
  • Active high ENABLE input.
  • Active high READY open-drain output.
  • High impedanc.

Control circuitry prevents the backplane from being connected to the card until a stop command or bus idle occurs on the backplane without bus contention on the card. When the connection is made, the PCA9510 and PCA9511 provides bi-directional buffering, keeping the backplane and card capacitances isolated.
