The TCA9517A is a BiCMOS integrated circuit intended for I2C bus and SMBus systems. It can provide bidirectional voltage-level translation (up-translation/down-translation) between low voltages (down to 0.9 V) and higher voltages (2.7 V to 5.5 V) in mixed-mode applications. This device enables I2C and similar bus systems to be extended, without degradation of performance even during level shifting. The TCA9517A buffers both the serial data (SDA) and the serial clock (SCL) signals on the I2C bus, thus allowing two buses of 400-pF bus capacitance to be connected in an I2C application. This device can also be used to isolate two halves of a bus for voltage and capacitance. The TCA9517A has two types of drivers—A-side drivers and B-side drivers. All inputs and I/Os are overvoltage tolerant to 5.5 V, even when the device is unpowered (VCCB and/or VCCA = 0 V). The TCA9517A offers a higher contention level threshold, VILC, than the TCA9517 and can be used in applications where a larger input logic low is required on the B-side.

Copyright © 2012–2013, Texas Instruments Incorporated TCA9517A SCPS245A – DECEMBER 2012 – REVISED APRIL 2013 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. DESCRIPTION/ORDERING INFORMATION (CONTINUED) The B-side drivers operate from 2.7 V to 5.5 V. The output low level for this internal buffer is approximately 0.5 V, but the input voltage must be 70 mV or more below the output low level when the output internally is driven low. The higher-voltage low signal is called a buffered low. When the B-side I/O is driven low internally, the low is not recognized as a low by the input. This feature prevents a lockup condition from occurring when the input low condition is released. This type of design on the B side prevents it from being used in series with the PCA9515B and another TCA9517A (B side). This is because these devices do not recognize buffered low signals as a valid low and do not propagate it as a buffered low again. The A-side drivers operate from 0.9 V to 5.5 V and drive more current. They do not require the buffered low feature (or the static offset voltage). This means that a low signal on the B side translates to a nearly 0-V low on the A side, which accommodates smaller voltage swings of lower-voltage logic. The output pulldown on the A side drives a hard low, and the input level is set at 0.3 VCCA to accommodate the need for a lower low level in systems where the low-voltage-side supply voltage is as low as 0.9 V. The A side of two or more TCA9517As can be connected together to allow a star topography, with the A side on the common bus. Also, the A side can be connected directly to any other buffer with static- or dynamic-offset voltage. Multiple TCA9517As can be connected in series, A side to B side, with no buildup in offset voltage and with only time-of-flight delays to consider. Because of the buffered low voltage from the B side, the TCA9517 cannot be connected B side to B side or the B side cannot be connected to a device with rise time accelerators. The TCA9517A drivers are enabled when VCCA is above 0.8 V and VCCB is above 2.5 V. The TCA9517A has an active-high enable (EN) input with an internal pullup to VCCB, which allows the user to select when the repeater is active. This can be used to isolate a badly behaved slave on power-up reset. The EN input should change state only when the global bus and repeater port are in an idle state, to prevent system failures. The TCA9517A includes a power-up circuit that keeps the output drivers turned off until VCCB is above 2.5 V and the VCCA is above 0.8 V. VCCB and VCCA can be applied in any sequence at power up. After power up and with the EN high, a low level on the A side (below 0.3 VCCA) turns the corresponding B-side driver (either SDA or SCL) on and drives the B side down to approximately 0.5 V. When the A side rises above 0.3 VCCA, the B-side pulldown driver is turned off and the external pullup resistor pulls the pin high. When the B side falls first and goes below 0.3 VCCB, the A-side driver is turned on and the A side pulls down to 0 V. The B-side pulldown is not enabled unless the B-side voltage goes below 0.4 V. If the B-side low voltage does not go below 0.5 V, the Aside driver turns off when the B-side voltage is above 0.7 VCCB. If the B-side low voltage goes below 0.4 V, the Bside pulldown driver is enabled, and the B side is able to rise to only 0.5 V until the A side rises above 0.3 VCCA. VCCA is only used to provide the 0.3 VCCA reference to the A-side input comparators and for the power-gooddetect circuit. The TCA9517A logic and all I/Os are powered by the VCCB pin. As with the standard I2C system, pullup resistors are required to provide the logic-high levels on the buffered bus. The TCA9517A has standard open-drain configuration of the I2C bus. The size of these pullup resistors depends on the system, but each side of the repeater must have a pullup resistor. The device is designed to work with Standard mode and Fast mode I2C devices in addition to SMBus devices. Standard mode I2C devices only specify 3 mA in a generic I2C system, where Standard mode devices and multiple masters are possible. Under certain conditions, higher termination currents can be used. 2 Submit Documentation Feedback Copyright © 2012–2013, Texas Instruments Incorporated Product Folder Links: TCA9517A TCA9517A www.ti.com SCPS245A – DECEMBER 2012 – REVISED APRIL 2013 TERMINAL FUNCTIONS NO.

In this example, the system master is running on a 3.3-V I2C bus, and the slave is connected to a 1.2-V bus. Both buses run at 400 kHz. Master devices can be placed on either bus. The TCA9517A is 5-V tolerant, so it does not require any additional circuitry to translate between 0.9-V to 5.5-V bus voltages and 2.7-V to 5.5-V bus voltages. When the A side of the TCA9517A is pulled low by a driver on the I2C bus, a comparator detects the falling edge when it goes below 0.3 VCCA and causes the internal driver on the B side to turn on, causing the B side to pull down to about 0.5 V. When the B side of the TCA9517A falls, first a CMOS hysteresis-type input detects the falling edge and causes the internal driver on the A side to turn on and pull the A-side pin down to ground. In order to illustrate what would be seen in a typical application, refer to Figure 8 and Figure 9. If the bus master in Figure 6 were to write to the slave through the TCA9517A, waveforms shown in Figure 8 would be observed on the A bus. This looks like a normal I2C transmission, except that the high level may be as low as 0.9 V, and the turn on and turn off of the acknowledge signals are slightly delayed. On the B-side bus of the TCA9517A, the clock and data lines would have a positive offset from ground equal to the VOL of the TCA9517A. After the eighth clock pulse, the data line is pulled to the VOL of the slave device, which is very close to ground in this example. At the end of the acknowledge, the level rises only to the low level set by the driver in the TCA9517A for a short delay, while the A-bus side rises above 0.3 VCCA and then continues high. 1.2 V 3.3 V 10 kW BUS MASTER 400 kHz 10 kW VCCB 10 kW VCCA 10 kW SDA SDAB SDAA SDA SCL SCLB SCLA TCA9517A SCL SLAVE 400 kHz EN BUS B BUS A Figure 6. Typical Application VILC AND PULL-UP RESISTOR SIZING For the TCA9517A to function correctly, all devices on the B-side must be able to pull the B-side below the voltage input low contention level (VILC). This means that the VOL of any device on the B-side must be below 0.45V. VOL of a device can be adjusted by changing the IOL through the device which is set by the pull-up resistance value. The pull-up resistance on the B-side must be carefully selected to ensure that logic levels will be transferred correctly to the A-side.

In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
