LTC2914HDHC-1#TRPBF

Supervisors Overview

The LTC2914HDHC-1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails. It features four independent channels capable of monitoring both under-voltage and over-voltage conditions for positive and negative supply voltages. The device operates within a wide supply voltage range and includes adjustable thresholds to accommodate various system requirements. Packaged in a compact DFN-16 surface-mount format, it integrates precision comparators with hysteresis to ensure stable operation during transient events. This component belongs to the LTC2914 series and is classified under PMIC - Power Management ICs.

Supervisors Feature Summary

• Monitors four independent voltage channels for simultaneous under-voltage and over-voltage detection across positive and negative supplies
• Provides precise threshold comparison with integrated hysteresis to prevent false triggering during signal transitions
• Supports flexible configuration through external resistor networks for custom voltage monitoring points

Supervisors Applications

• Multi-rail power supply monitoring in industrial control systems
• Voltage supervision in telecommunications infrastructure equipment
• System integrity monitoring in automotive electronic control units

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing from distributors. Confirm the manufacturer part number matches Analog Devices Inc. documentation exactly. Check RoHS compliance status via official datasheets or certified supplier declarations. Ensure the DFN-16 package variant aligns with PCB footprint specifications before procurement.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision is required for both polarities. Compare quiescent current specifications against other LTC291x variants if power efficiency is critical. Verify that the adjustable threshold capability meets the specific voltage levels of the target application. Consider the DFN-16 package size constraints relative to available board space.

Supervisors Part Context

This part is part of the LTC2914 family of supervisory circuits from Analog Devices. It shares functional similarities with other members like the LTC2911 and LTC2912 but offers distinct channel counts and polarity support. The HDHC-1 designation specifies the thermal grade and pin configuration within the broader product line.
