General description
The PCA9510A is a hot swappable I
2
C-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 PCA9510A provides bidirectional buffering, keeping the
backplane and card capacitances isolated.
The PCA9510A has no rise time accelerator circuitry to prevent interference when there
are multiple devices in the same system. The PCA9510A 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 PCA9510A SDAIN and SCLIN pins (inputs only) are precharged to
1 V to minimize the current required to charge the parasitic capacitance of the chip.
Remark:
The dynamic offset design of the PCA9510A/11A/12A/13A/14A I/O drivers allow
them to be connected to another PCA9510A/11A/12A/13A/14A device in series or in
parallel and to the A side of the PCA9517. The PCA9510A/11A/12A/13A/14A
cannot
connect to the static offset I/Os used on the PCA9515/15A/16/16A/18 or PCA9517 B side
or P82B96 Sx/y side.
