Part Number: TCA9517-Q1 Hi Team,
We want to use TCA9517-Q1 as I2C buffer, and here are a few questions for this TCA9517-Q1 IC: (1) If the master I2C device is an I2C analog with GPIO, is this still applicable? (2) How many (3~4) device addresses are…
Part Number: TCA9517 Tool/software: We want to add a pull - down resistor to the EN pin of TCA9517 so that it defaults to low level after power - up, and we can pull it high via MCU when needed. However, the datasheet states that there is an internal…
Part Number: TCA9517 Tool/software: Hi!
In my application I will use I2c as output from device for non-standard frequency 10 kHz in automotive application.
I want to use TCA9517 (or other I2C repeater) as protection against external transients.…

Hi Expert,
My customer uses the TCA9517 in the following circuit. Please help to review the schemtic shown as below. Customer referenced the datasheet for the design, connecting 3.3V to the master and 1.8V to the slave.
Schematics…
Part Number: TCA9517 Other Parts Discussed in Thread: TXS0102 , , TCA9617B , Tool/software: I have a simple application of TCA9x17 where TCA9517 is not working but TCA9617 is. The A side is an iMX8 processor on a SoM and the B side is an HDMI I2C port…
Part Number: TCA9517 Tool/software: Hi team,
Since the device has internall pull up resistor for EN, if the customer wants the IC to be always active, can they left the EN pin floating?

Part Number: TCA9517-Q1 Hi,
In the datasheet it is stated that "the EN input should only change state when the global bus and repeater port are in an idle state, to prevent system failures".
In the event that either the global bus AND/OR the repeater…
Part Number: TCA9517-Q1 Tool/software: hi TI expert We use a structure similar to the one shown in the figure to design an MCU with 3.3V, which is converted to a 1.8V level through LEVELSHIFT. Occasional MCU I2C card dead situation, test BUS-B with SCL…
