Hi TI,
we have been looking into TPS40400 to supply 1.00V core voltage for a CPU. We think the current can be up to 10A, therefore we will use the voltage sense function that this part have.This CPU will handle the I2C and PMBus for TPS40400.
We would like to use the POWER GOOD from the TPS40400 to be one of the signals that control the RESET for the CPU, but this looks impossible since the default value setting for POWER_GOOD_ON is 1.104V. We would get 1.00V out because of the resistor setting, but POWER GOOD would never be true.
Can you confirm this? Do you know any work-around other than skipping the POWER GOOD signal?
regards
