LTC2914CGN-2#PBF

Supervisors Overview

The LTC2914CGN-2#PBF is a quad input voltage monitor designed for simultaneous supervision of multiple power rails. It features adjustable threshold voltages with a guaranteed accuracy of ±1.5% over the operating temperature range. The device operates within an input voltage range of 2.3V to 6.6V and draws a typical supply current of 70µA. It provides open-drain outputs and includes a reset delay time of 8.5ms. The component is housed in a 16-lead SSOP package and supports commercial temperature operation from 0°C to +70°C.

Supervisors Feature Summary

• Simultaneous monitoring of four independent voltage inputs using dual pins per channel
• Adjustable threshold detection for both positive and negative voltage excursions
• Integrated buffered 1V reference output for external threshold setting flexibility
• Open-drain reset output compatible with various logic families

Supervisors Applications

• Multi-rail power supply supervision in industrial equipment
• Voltage monitoring in embedded systems requiring multiple power domains
• Battery management systems tracking several cell or rail voltages
• Telecommunications infrastructure power integrity verification

Supervisors Procurement Notes

Verify the specific suffix CGN indicates the commercial temperature grade (0°C to +70°C) and SSOP package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the 2.3V to 6.6V operating range and 70µA quiescent current requirements for the target application environment.

Supervisors Selection Notes

Select this component when simultaneous supervision of four distinct voltage rails is required without external comparator complexity. The adjustable thresholds allow customization for specific UV/OV limits via external resistors. Consider the 16-SSOP package constraints and commercial temperature range suitability against system environmental specifications and board space limitations.

Supervisors Part Context

This part belongs to the LTC2914 family of quad voltage monitors manufactured by Analog Devices. It shares functional similarities with other members like the LTC2914HDHC-2#PBF but differs in package type and temperature rating. The series is designed for applications needing reliable multi-voltage oversight with high accuracy and low power consumption.

Supervisors Replacement Considerations

Direct substitutes include other variants within the LTC2914 family, such as the LTC2914HDHC-2#PBF, noting differences in package and temperature range. Verify pinout compatibility and electrical parameter alignment before substitution.
