The ADM6819 and ADM6820 are simple power supply sequencers with FET drive capability for enhancing N-channel MOSFETs. These devices can monitor a primary supply voltage and enable/disable an external N-channel FET for a secondary supply. The ADM6819 has the ability to monitor two supplies. When more than two voltages require sequencing, multiple ADM6819/ADM6820 devices can be cascaded to achieve this. The devices operate over a supply range of 2.95 V to 5.5 V.
