We have designed a circuit using this chip with the 3.3 voltage rail . Without converting it to 2.8 as it is bellow the max thresh-hold as per the datasheet.
We also pulled up the XSHUT pin high to 3.3v using a 10k ohm resistor. In theory it should put the device into a software standby state. But the device doesn't turn on.
The only way we were able to turn on the device on was directly connecting the 3.3 v to the XSHUT pin, but it fails to do any sort of ranging.
We followed the Application schematic, described on the datasheet.
Any help will be greatly appreciated.
