Part Number: TCA9539-Q1 Hello,
I'm considering using the TCA9539-Q1 in a new design. I've studied the datasheet and can't find any statement on the electrical connection for the Thermal Pad, pin25, for the VQFN & WQFN packages. On some…
Part Number: TCA9539-Q1 Hi team,
If I/O is configurated as an input, is there an internal current limit resistor?
I see below diagram doesn't show the resistor.
Thanks!
Part Number: TCA9539-Q1 Hello,
I'm checking the TCA9539-Q1 to apply this on my ECU.
I couldn't find the recommended the bypass capacitance on VCC,
Could you let me know this value or related document to calculate the bypass capacitance?
Part Number: TCA9539-Q1 Hi Team,
Customer using TCA9539-Q1, the I2C bus also connected 10 other devices like temp sensors. But other devices' leakage current are very small (uA level)
From datasheet page 18, SLVA689, the min pull up resistor is 967…

Dear expert,
In customer system, occasionally, there is pulse 16V signal appear at Pxx pin. (Max current is 1mA. 16V duration is 60s. sometimes, 35V/300ms)
Can TCA9539 reliability be guaranteed…
Part Number: TCA9539-Q1 Other Parts Discussed in Thread: TCA9539 HI TI Expert,
as sch show below, during MCU standby mode, TCA9539 reset pin will be pull down, will the INT pin still action correctly when there is a tigger on input port ?

Part Number: TCA9539-Q1 Hi
I need TI's expert to confirm the status of TCA9539-Q1's GPIO (P0-P7, P10-P17) after Vcc is powered but bedore reset is enabled.
Regards,
Vincent
