Tool/software:
Hello,
I would like to monitor the current flowing through the TPS1685 using the IMON pin.
The voltage on the IMON pin will be passed through an op-amp in a non-inverting amplifier configuration, before entering an A/D.
However, since the TPS1685 will server as the main power entry point, the op-amp will not be powered during the start-up phase of the hot swap.
I'm worried that the IMON current source will be loaded by the unpowered op-amp positive input, which may cause start up issues.
Will it be safer to use ILIM as the current monitor (since it doesn't effect the start-up phase)?
Thanks for the help,
Alex
