LTC2914IDHC-1#TRPBF

Supervisors Overview

The LTC2914IDHC-1#TRPBF 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 supply lines. The device operates within a supply voltage range of 1.7V to 5.5V and draws a typical quiescent current of 70µA. It utilizes a 16-lead DFN package and provides open-drain reset outputs with a fixed 200ms reset delay time.

Supervisors Feature Summary

• Monitors four independent voltage inputs for under-voltage and over-voltage events
• Supports detection on both positive and negative supply rails
• Provides open-drain reset output signals with configurable timing

Supervisors Applications

• Multi-rail power system supervision in industrial equipment
• Voltage monitoring in embedded computing systems
• Power integrity verification in telecommunications infrastructure

Supervisors Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when sourcing from distributors. Confirm the 'I' grade designation matches required operating temperature ranges for your application environment. Cross-reference the datasheet revision date to ensure compatibility with current design specifications and pinout definitions.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required, including negative supplies. Consider the 70µA quiescent current for low-power applications. Ensure the 16-lead DFN footprint fits the PCB layout constraints. Verify that the 200ms reset delay aligns with system startup timing requirements.

Supervisors Part Context

This part belongs to the LTC2914 series of multi-channel voltage supervisors. It complements other Analog Devices monitoring solutions like the LTC2910 (octal) and LTC2912 (single channel). The IDHC-1 variant specifically denotes industrial temperature range performance and the -1 suffix indicates the reset threshold configuration.

Supervisors Replacement Considerations

Direct substitutes include the LTC2914HDHC-1#PBF for tube packaging or the LTC2914EDHC-1#TRPBF for extended temperature range. Verify pin compatibility and electrical parameters before substitution.
