PMP10711, Simple 6-Channel Power Supply Sequencing Reference Design for Multi-rail Outputs

PMP10711, Simple 6-Channel Power Supply Sequencing Reference Design for Multi-rail Outputs. The PMP10711 is a 6-channel power supply sequencer that utilizes two LM3880 3-channel sequencer ICs. The design uses an external and gate and OR gate to power up and power down all 6 channels in sequential fashion. This is useful in cases when up to 6 power rails need to be sequenced during power up and power down
