LTC2928CUHF#TRPBF

Supervisors Overview

The LTC2928CUHF#TRPBF is a multichannel power supply sequencer and supervisor manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 38-pin QFN package. The device supports up to four independent channels for sequencing and monitoring power rails. It features adjustable threshold voltages for supervision and includes programmable delay times to control the startup sequence of multiple power supplies.

Supervisors Feature Summary

• Provides precise sequencing and supervision for multiple power rails
• Features adjustable voltage thresholds for flexible monitoring configurations
• Supports programmable delay times to manage startup sequences

Supervisors Applications

• Multichannel power supply sequencing systems
