PCA9510 Hot Swappable I2C-bus And SMBus Bus Buffer

The PCA9510 is a hot swappable I2C-bus and SMBus Buffer that allows I/O card insertion into a live Backplane without corrupting the data and Clock buses. 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 provides bidirectional buffering, keeping the Backplane and card capacitances isolated. The PCA9510 has no rise time accelerator circuitry to prevent interference when there are multiple devices in the same system. The PCA9510 incorporates a digital ENABLE input pin, which enables the device when asserted HIGH and forces the device into a low current mode when asserted LOW, and an open-drain READY output pin, which indicates that the Backplane and card sides are connected together (HIGH) or not (LOW). During insertion, the PCA9510 (IN only) SDA and SCL lines are precharged to 1 V to minimize the current required to charge the parasitic capacitance of the chip. The dynamic offset design of the PCA9510 11/12/13/14 I/O drivers allow them to be connected to another PCA9510 11/12/13/14 device in series or in parallel and to the A side of the PCA9517. The PCA9510 11/12/13/14 CAN not connect to the static offset I/Os used on the PCA9515 15A/16/16A/17 B side and PCA9518.
