Input tolerance of GPIO-OVT on CYBLE-012011-00

[japac_1817436]

What is the input tolerance of the OVT pins P5.0 and P5.1 on CYBLE-012011-00?

   

I can't seem to find an exact value in any of the datasheets.

   

I would like to connect one of the OVT pins through a series resistor with adequate value to the voltage source (+5V) of a USB port in order to identify whether the device is connected to a USB port or not.

   

Thank you in advance.

Hi,

   

The Voltage on the OVT pins can go upto 6V. Please refer the Cy Pins component datasheet of Creator. Attached the same.

   

Thanks,

Thank you. I have one more question.

   

I found the mentioning of the input tolerance of GPIO_OVT pins in the 'Hot Swap' section.

   

Does this mean that the pin must be 'Hot swap' enabled and mapped to any of the GPIO_OVT pins (P5.0 or P5.1) for it to be 6V tolerant? Just want to make sure.

   

Thanks again.

Hi,

   

Please refer Pg:37 of the component datasheet.

   

A GPIO_OVT pin is used if any of the following parameters is set.
□ Hot Swap is set to true
□ Slew Rate is set to I2C FM+, or I2C HS
□ Drive Current is set to 10mA sink

   

Thanks,
