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-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 Other Parts Discussed in Thread: PCA9306 Tool/software: TCA9517-Q1 is labeled as VSSOP-8 but is really more like MSOP-8
PCA9306 is also labeled as VSSOP-8 ... but is not the same ???
Please fix one of them, and do not use same…
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…
Part Number: TCA9517-Q1 Tool/software: We use TCA9517DGKRQ1 in our design.
The datasheet mentions that there is an internal pullup resistor on the EN pin.
Can you please tell me the value of this internal pullup resistor? I did not find this in the…
Hi Akeem,
These hitches or pedestals are normal operation for the TCA9517-Q1.
See figure 10-4 and Figure 10-5 of the TCA9517-Q1 datasheet on page 15 of 26:
I agree with Clemens, VOLB is a larger voltage (~0.52V) when driving a LOW from A-side…
Part Number: TCA9517-Q1 Other Parts Discussed in Thread: BQ24780S TCA9517-Q1 Hi,
In my application, I have a battery charger chip (BQ24780S) and a battery BMS (some BQ chip I don't know precisely) talking together on a shared SMBus, and a FPGA sending…
Part Number: TCA9517-Q1 Tool/software: Hello everyone,
I need to calculate the pull-up resistor value for an I2C bus, but this bus is about 1 meter from my main board. I need to consider the cable length in that case. Does anyone know how to calculate…
Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TCA9517
hi，
1. As shown in the following figure, how is the latch triggered? Can it be restored? If the latch is triggered, how can the chip electrical signal be determined?
2. As shown…
Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TCA9517 Hello team,
Would you please confirm if the following configuration of TCA9517-Q1 is available?
Thanks,
