LTC2902-1CGN#PBF

Supervisors Overview

The LTC2902-1CGN#PBF is a programmable four-channel supply monitor manufactured by Analog Devices Inc. It supports up to four independent voltage monitoring channels with selectable thresholds from 16 preset options or adjustable settings. The device features an adjustable reset timer and power-fail detection capabilities. It operates within a supply voltage range of 2.7 V to 5.5 V and is housed in a 16-lead SSOP package. The component is designed for systems requiring precise supervision of multiple power rails.

Supervisors Feature Summary

• Programmable multi-voltage supervision for up to four independent power rails
• Adjustable reset timer functionality for customizable timing control
• Selectable voltage threshold combinations from predefined presets or user-adjustable values

Supervisors Applications

• Systems with multiple supply voltages requiring simultaneous monitoring
• Embedded applications needing programmable power-fail detection
• Industrial equipment supervising critical power rails

Supervisors Procurement Notes

Verify the exact part number suffix, specifically #PBF, to confirm lead-free compliance and packaging type. Ensure the order matches the specific variant (e.g., -1C) as different suffixes may indicate variations in temperature range or reel quantity. Cross-reference with official Analog Devices documentation to confirm current availability status and valid ordering codes before finalizing procurement.

Supervisors Selection Notes

Select this component when designing systems that require supervision of up to four distinct voltage levels. The choice depends on the need for programmable thresholds rather than fixed comparator circuits. Consider the 16-lead SSOP package constraints and the operating voltage range requirements. This IC is suitable where space efficiency and configurable monitoring logic are prioritized over simple single-supervisor solutions.

Supervisors Part Context

The LTC2902 series belongs to Analog Devices' portfolio of supervisory circuits. These devices are engineered for precision power management in complex electronic systems. The -1CGN#PBF variant specifically denotes the commercial temperature grade and narrow SSOP packaging. It serves as a dedicated solution for multi-rail power integrity verification in compact form factors.

Supervisors Replacement Considerations
