Triple Voltage Monitor with Power Good Signal
In order to monitor multiple power supply voltages it is possible to use one comparator per voltage, coupled with some logic to combine the output signals and, for example, generate a reset signal for a microprocessor.Things are simpler with the LTC1727 from Linear Technology (www.linear-tech.com/pdf/17278fa.pdf). This IC is available in different voltage variants.
