TPS62861: TPS628610YCHR Design Queries

Hi Moheddin,

1. What is the main purpose of VSEL pin?

2. How can we program IC through I2C interface, is there any TI tool for it?

Thanks

Hi Moheddin,

1. Is it necessary to connect to GUI using USB to ANY TI tool?

2. What is the soft start time of IC, is it adjustable?

Thanks

Hi Moheddin,

1. Is it ok if i use this cable(TTL-232RG-VREG1V8-WE) to connect to GUI using I2C, Is it possible?

Thanks

Hi Moheddin,

1. Is there any specified pull-up resistor which needs to be provided to SCL and SDA lines, because the IC slave address is not getting detected.

Thanks

Hello Nachiketh Karanth,

Can you try with 2kOhm pull-up resistor.

Thank you & regards,

Moheddin.

Hi Moheddin,

1. What is the default slave address?

2. Even with 2K Ohm pull-up resistor the device is not getting detected.

3. Can we access the I2C registers in Linux PC, if we can will the values changed be retained or will the IC reset the values after a power cycle

Thanks

The 7-bit slave address is 0x40

Can you use this slave address and update.

Thank you & regards,

Moheddin.
