Analog Devices ADM6819/ADM6820 Power Sequencer Datasheet
The ADM6819 and ADM6820 are simple power‑supply sequencers with FET‑drive capability that monitor a primary voltage and enable or disable an external N‑channel MOSFET for a secondary supply. They support sequencing of two supplies (ADM6819) or a single‑supply version with adjustable delay (ADM6820) and can be cascaded for multi‑voltage systems.
Key features include an on‑board charge pump, adjustable primary‑supply monitor, fixed 300 ms delay for the ADM6819, capacitor‑adjustable delay for the ADM6820, and operation over a 2.95 V to 5.5 V supply range. The devices are supplied in a 6‑lead SOT‑23 package.
