LTC2928IUHF#TRPBF

Supervisors Overview

The LTC2928IUHF#TRPBF is a multichannel power supply sequencer and supervisor manufactured by Analog Devices Inc. It features four independent channels with adjustable or selectable reset threshold voltages, providing robust supervision for complex power systems. The device operates within an extended temperature range of -40°C to +85°C and is housed in a compact 38-pin QFN package with an exposed pad (5x7 mm). Designed for safety-critical applications, it ensures reliable system startup and shutdown sequences while monitoring voltage levels.

Supervisors Feature Summary

• Multichannel sequencing capability for coordinated power-up and power-down sequences
• Adjustable or selectable reset threshold voltages for flexible supervision requirements
• Low active current consumption for efficient power management
• Robust fault detection and reporting mechanisms for system reliability

Supervisors Applications

• Safety-critical automotive electronics
• Industrial control systems requiring precise power sequencing
• Telecommunications infrastructure equipment
• Medical devices with strict power supervision needs

Supervisors Procurement Notes

Verify the exact part number suffix (#TRPBF) indicates tape-and-reel packaging when ordering. Confirm compatibility with your system's voltage rails and timing requirements against official datasheets. Ensure proper ESD handling during installation due to the exposed pad thermal design. Cross-reference with authorized distributors to confirm current availability status.

Supervisors Selection Notes

Select this component when multiple power rails require synchronized sequencing and supervision. Consider the 38-pin QFN package size constraints and thermal dissipation needs. Evaluate if adjustable reset thresholds meet specific voltage monitoring requirements compared to fixed-threshold alternatives. Verify operating temperature range suitability for your application environment.

Supervisors Part Context

Part of the LTC2928 family of power sequencers and supervisors from Analog Devices. Shares core functionality with variants like LTC2928IUHF#PBF (tube packaging) but differs in delivery format. Related to other PMIC solutions in the Linear Technology portfolio designed for complex power management tasks.

Supervisors Replacement Considerations

LTC2928IUHF#PBF offers identical electrical characteristics with tube packaging instead of tape-and-reel. No direct functional substitutes are documented; verify pinout and parameter compatibility before considering alternative manufacturers' components.
