LTC2914CGN-1#PBF

Supervisors Overview

The LTC2914CGN-1#PBF is a quad input voltage monitor from Analog Devices, designed for supervising multiple power rails in complex electronic systems. It operates within a supply voltage range of 2.7V to 36V and features an operating supply current of 70µA. The device provides adjustable under-voltage and over-voltage thresholds with a guaranteed accuracy of ±1.5% across the temperature range. It supports monitoring up to four positive voltages and two negative voltages, utilizing dual inputs per channel for enhanced noise immunity.

Supervisors Feature Summary

• Simultaneous monitoring of four distinct voltage channels
• Adjustable under-voltage and over-voltage trip points
• High threshold accuracy maintained across full temperature ranges
• Input interference suppression for reliable operation

Supervisors Applications

• Multi-rail power system supervision
• Industrial control board monitoring
• Telecommunications equipment power management
• Embedded system voltage tracking

Supervisors Procurement Notes

Verify the specific suffix 'GN' indicates the SSOP-16 package variant when sourcing replacements. Confirm that the '#PBF' designation ensures lead-free compliance and RoHS standards. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure authenticity and correct revision level before integration into production designs.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four independent voltage lines is required without external logic. The adjustable threshold capability allows customization for specific rail tolerances. Consider the 70µA quiescent current for power-sensitive applications. Ensure the SSOP-16 package fits the available PCB footprint constraints compared to other package options in the series.

Supervisors Part Context

This part belongs to the LTC2914 family of quad voltage monitors. It shares core functionality with variants like the LTC2914HDHC-1 but differs in package type and thermal characteristics. The CGN-1#PBF specifically denotes the green SSOP-16 plastic package version, distinguishing it from DFN or MSOP alternatives within the same product line.

Supervisors Replacement Considerations

Direct pin-compatible substitutes include other LTC2914 package variants such as LTC2914HDHC-1#PBF, provided the package change is acceptable for the design.
