Dual-/Triple-Voltage, Power-Supply Sequencers/Supervisors

General Description 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 volt ages to the system sequentially, enhancing n-channel MOSFETs used as swi
