概述
The TPT29511B device is a dual bidirectional I2C and SMBus Hot-swap buffer with an enable (EN) input, and work from 2.3 V to 5.5 V VCC, which supports IO cards live insertion and removal from backplane. Control circuit prevents the backplane-side I2C lines (in) from the other card-side I2C lines (out) until a stop command or bus idle condition occurs on the backplane without bus contention on the card. When the connection is made, the TPT29511B provides bidirectional buffering, keeping the backplane and card capacitances isolated.
The TPT29511B rise time accelerator circuitry allows the use of weaker DC pull-up currents while still meeting rise time requirements (ΔV/Δt > 1.25 V/us). when the pulse width of the rise edge acceleration is greater than 300 ns, the ACK error protection is triggered to prevent the direction switching error.
The TPT29511B 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).
TPT29511B is available in MSOP8 and SOP8 package, and is characterized from −40°C to +125°C.
