PCA9511
Datasheet
General description
The PCA9511 is a are 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 PCA9511 provides bidirectional buffering, keeping the backplane and card capacitances isolated.
The PCA9511 rise time accelerator circuitry allows the use of weaker DC pull-up currents while still meeting rise time requirements to prevent interference when there are multiple devices in the same system. The PCA9511 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 PCA9511 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.
Features
- Bidirectional 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-bus Standard-mode, I2C-bus Fast-mode, and SMBus standards
- ΔV/Δt rise time accelerators on all SDA and SCL lines
- Rise time accelerator threshold of 0.6 V
- Active HIGH ENABLE input
- Active HIGH READY open-drain output
- High-impedance SDA and SCL pins for VCC = 0 V
- 1 V precharge on all SDA and SCL lines
- Supports clock stretching and multiple master arbitration/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)
