"How to Configure an I2C Push-Pull IO Expander to Operate as Open-Drain?"
Part Number: AM62A3 Other Parts Discussed in Thread: TCA6424 , TPS22918 Tool/software: Hello, TI Expert
Follow title description, customer design AM62A SOM and try to remove un-necessary parts & nets for AM62A_LP EVM design. We reference schematic as below…
Part Number: SK-AM62 Other Parts Discussed in Thread: TCA6424 , Tool/software: Hi, Dear Expert
The goal of this thread is try to let "uart1" of M.2 slots real inter-connect to AM62x uart1 (A18/B19/E19/A20)
So we need try to study how does TCA6424…
Part Number: J722SXH01EVM
This IO expander is on I2C ADDRESS: 0x22 and reads the boot pins.
It also has buffers which isolate it from the pin configuration during normal operation.
Is the IO expander required for any operation of J722S (u-boot USB DFU…
Part Number: P82B96 Tool/software: Hi Team,
My customers are trying to use I2C as a local bus to expand IOs by using the I2C buffer to boost the range (up to 3m) and improve the noise suppression.
These modules being part of their security system will…
Part Number: IO-EXPANDER-EVM Other Parts Discussed in Thread: TCA6424 , TCA6416 , TCA9535 , TCA9534 Good evening,
On my design board , which is battery powered, I need to optimize the power consumption during sleep mode ( 40uA at 3.3V) , pull-up resistors on…
Hi,
Vaibhav Kumar said: Before we move forward, can you please specify which exact EVM you are using:
I am using the red SK-AM64B you have.
Vaibhav Kumar said: On that note, would you like me to send you a cpiece of working code which basically sets one…
Part Number: IO-EXPANDER-EVM Other Parts Discussed in Thread: TCA6416A , USB2ANY , TCA6424 , TCA6416 , TCA9539 , TCA6424A I have IO Expander EVM board with TCA6416A installed. It's address pin is pulled up by design, so the address is 0x21. I send a dummy data…
Part Number: PCA9535 Other Parts Discussed in Thread: IO-EXPANDER-EVM , TCA9535 Hello,
Can the IO Expander EVM be used to evaluate PCA9535PWR?
Thanks,
