Abstract
A power monitor circuit and method delays the start of a computer until multiple power lines are at a safe level of operation. The integrated circuit monitors only the voltage of a primary power supply output and eliminates the need for monitor circuits on each supply output. The power supply is made to exacting specifications that tie the 5 volt and 3.3 volt supplies to the primary 12 volt supply. The ATX power supply drives the 3.3 and 5.0 supplies to reach 90% of their values within 40 ms after the 12 volt supply reaches 90% of its value. A time delay circuitdelays switching the 3.3 and 5 volt dual outputs from the standby voltage supply to the active voltage supplies until after the primary 3.3 and 5 volt are at a safe operating level.
