ADM6820 - (ADM6819 / ADM6820) FET Drive Simple Sequencers

This page provides the datasheet information for the ADM6820, a member of the ADM6819 (ADM6819 / ADM6820) FET Drive Simple Sequencers family.

Description

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.

Features

  • Single chip enables power supply sequencing of two supplies On-board charge pump fully enhances N-channel FET Adjustable primary supply monitor to 0.618 V Delay from primary supply to secondary supply enabled Fixed 300 ms delay (ADM6819) Capacitor adjustable delay (ADM6820) Logic/analog driven enable input (ADM6819).
  • 40°C to +85°C operating range Packaged in small 6-lead SOT-23 package Pin-to-pin compatibility with MAX6819/MAX6820 VCC1 VCC2 VCC1 VCC2 CHARGE PUMP UVLO R1 SETV 0.618V LOGIC.
