概述
The TPT29511H device is a dual bidirectional I2C and SMBus hot-swap buffer with an enable (EN) input, and works from 2.3 V to 5.5 V VCC, which supports IO cards live insertion and removal from the backplane. The 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 TPT29511H provides bidirectional buffering, keeping the backplane and card capacitances isolated.
The TPT29511H rise time accelerator circuitry allows the use of weaker DC pull-up currents while also meeting rise time requirements (ΔV/Δt > 0.6 V/us).
The TPT29511H 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 (high) or not (low).
TPT29511H is available in the MSOP8 package, and is characterized from −40°C to +125°C.
