General description

The PCA9513 and PCA9514 are hot swappable I2C and SMBus buffers 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 PCA9511, PCA9513, and PCA9514 provides bi-directional 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 PCA9513 and PCA9514 incorporate 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 PCA9513 supplies a 92 uA current source to SCLIN and SDAIN in lieu of using pull-up resistors for PICMG backplane 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 VCC.

PCA9513 and PCA9514 rise time accelerator threshold is 0.8 V to provide improved noise margin over the PCA9510 and PCA9511.

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.

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
  • ΔV/Δt rise time accelerators on all SDA and SCL lines
  • 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 SDA and SCL pins for VCC = 0 V
  • 92 uA current source on SCLIN and SDAIN for PICMG backplane applications (PCA9513 only)
  • Supports clock stretching and multiple master arbitration/synchronization
  • Operating power supply voltage range: 2.7 V to 5.5 V
  • 5.5 V tolerant I/Os
  • 0 kHz 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)
