MAX6819 Datasheet Sot23 Power-supply Sequencers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-1951; Rev 2; 4/02 SOT23 Power-Supply Sequencers General.

General Description

The MAX6819/MAX6820 are power-supply sequencers for dual-voltage microprocessors (µPs) and multivoltage systems.

These devices monitor a primary supply voltage and enable/disable an external N-channel MOSFET switch for a secondary supply voltage.

The MAX6819/MAX6820 control local ponent voltage sequencing when system power-on/power-off characteristics cannot be guaranteed (supplies e from a multivoltage system bus, silver box, or must be sequenced in different modes for ponents on the same board).

Key Features

  • a logic-driven EN input to enable/disable the external MOSFET drive and includes an internally fixed 200ms enable timeout period (V.
