The MAX6880MAX6883 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. The MAX6880/MAX6881 sequence three voltages and the MAX6882/MAX6883 sequence two voltages. These devices initially monitor all of the voltages and when all of them are within their tolerances, the internal charge pumps enhance external n-channel MOSFETs in a sequential manner to apply the voltages to the system. Internal charge pumps drive the gate voltages 5V above the respective input voltage thereby ensuring the MOSFETs are fully enhanced to reduce the on-resistance. |
