MAX6820 SOT23 Power-Supply Sequencers

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 component voltage s.

MAX6820 Features

* a logic-driven EN input to enable/disable the external MOSFET drive and includes an internally fixed 200ms enable timeout period (V PRIMARY GOOD to V SECONDARY ENABLE ). The MAX6820 allows the enable timeout period to be adjusted with a single external capacitor. Both devices are specified over the
