Hello,
I have designed in a TPS659113 Power Manager to supply volts to a TI8148 processor. I am totally unable to get the device up and running and your help would be much appreciated, All outputs seem to be in a sleep mode as I am not getting any voltages out from the device. Here is a copy of the circuit, it was taken from the Mistral EVM circuit.
There are volts in the device as PWRON is pullup to 5V, yet I cannot talk to the device over I2C from another I2C master. What voltage supply does the I2C slave within the chip require as I would expect to be able to talk to it. Or is there anything else that is preventing the I2C slave from responding?
Many thanks.
Dominic
