LTC2914IDHC-1#PBF

Supervisors Overview

The LTC2914IDHC-1#PBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails. It features four independent channels capable of detecting both under-voltage and over-voltage conditions on positive and negative supplies. The device operates within a supply voltage range of 2.7V to 5.5V and draws a typical quiescent current of 70µA. It utilizes a DFN-16 package suitable for surface-mount applications, providing precise threshold detection with an accuracy of 1.5% across the operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors four independent voltage inputs for simultaneous under-voltage and over-voltage events
• Supports detection of both positive and negative supply rail anomalies
• Provides open-drain fault output signals for system integration

Supervisors Applications

• Multi-rail power distribution systems in industrial equipment
• Server and storage backplane voltage supervision
• Telecommunications infrastructure power monitoring

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status through manufacturer datasheets. Ensure the DFN-16 package footprint aligns with PCB layout constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision is required without manual reset functionality. Compare quiescent current specifications against other supervisory ICs if power efficiency is critical. Verify that the 1.5% accuracy meets the tolerance requirements of the monitored circuits.

Supervisors Part Context

This part belongs to the LTC2914 series of supervisory circuits from Analog Devices. It shares functional similarities with the LTC2910 and LTC2912 but offers distinct channel counts and package options. The IDHC-1 variant specifies the industrial temperature grade and specific pin configuration within the broader product family.

Supervisors Replacement Considerations

Consult official cross-reference guides for verified substitutes. Direct replacements may include variants from the same series with different package styles or channel counts.
