MAX6883 Overview
The MAX6880 MAX6883 dual-/triple-voltage monitors are designed to sequence power supplies during power-up condition. When all of the voltages exceed their respective thresholds, these devices turn on voltages to the system sequentially, enhancing n-channel MOSFETs used as switches. The time between each sequenced voltage is determined by an external capacitor, thus allowing flexibility in delay timing.
