General description

The PCA9513A and PCA9514A are hot swappable I²C-bus and SMBus buffers that allow 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 PCA9513A and PCA9514A provides bidirectional buffering, keeping the backplane and card capacitances isolated.

Rise time accelerator circuitry allows the use of weaker DC pull-up currents while still meeting rise time requirements. The PCA9513A and PCA9514A 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).

The PCA9513A supplies a 92 uA current source to SCLIN and SDAIN pins in lieu of using pull-up resistors which is ideal for multidrop bus applications. Including the current source in the device provides for a consistent RC time constant as cards are removed and inserted into the backplane. The current source is high-impedance whenever the pin voltage is greater than the part V_CC.

The PCA9513A and PCA9514A rise time accelerator threshold is 0.8 V to provide better noise margin over the PCA9511A which is set to 0.6 V.

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.

Features

Bidirectional buffer for SDA and SCL lines increases fan-out and prevents SDA and SCL corruption during live board insertion and removal from multipoint backplane systems
Compatible with I²C-bus Standard mode, I²C-bus Fast mode, and SMBus standards
Built-in ΔV/Δt rise time accelerators on all SDA and SCL lines (0.8 V threshold) requires the bus pull-up voltage and supply voltage (V_CC) to be the same
Rise time accelerator threshold moved from 0.6 V to 0.8 V for improved noise margin
Active HIGH ENABLE input
Active HIGH READY open-drain output
High-impedance SDAn and SCLn pins for V_CC = 0 V
92 uA current source on SCLIN and SDAIN for PICMG backplane applications (PCA9513A only)
Supports clock stretching and multiple master arbitration and synchronization
Operating power supply voltage range: 2.7 V to 5.5 V
0 Hz to 400 kHz clock frequency
ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101
Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
Packages offered: SO8, TSSOP8 (MSOP8)
