LTC2914HGN-2#TRPBF

Supervisors Overview

The LTC2914HGN-2#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple power rails. It features four independent voltage monitor channels capable of detecting both under-voltage and over-voltage conditions on positive and negative supplies. The device utilizes an open-drain output configuration to signal fault states. It operates within a supply voltage range up to 7 V and maintains an accuracy of 1.5%. The component is housed in a 16-lead SSOP package and supports surface-mount installation. It functions reliably across an extended temperature range from -40°C to +125°C, with a reset delay time of 8.5 ms and a typical operating current of 70 µA.

Supervisors Feature Summary

• Monitors four independent input voltages for under-voltage and over-voltage faults
• Provides open-drain output signaling for fault detection
• Supports monitoring of both positive and negative supply rails

Supervisors Applications

• Multi-rail power system supervision in industrial equipment
• Voltage monitoring in embedded computing platforms
• Fault detection in battery-powered portable devices

Supervisors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the H-grade designation corresponds to the required extended temperature performance specifications. Ensure compatibility with the 16-SSOP footprint during PCB layout finalization. Cross-reference the manufacturer datasheet for any recent pinout or electrical characteristic updates prior to procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required without external comparator complexity. The adjustable threshold capability allows customization for various supply levels. Consider the low quiescent current for battery efficiency requirements. Verify that the open-drain output interface aligns with the downstream logic level requirements of the microcontroller or processor being supervised.

Supervisors Part Context

This part belongs to the LTC2914 series of supervisory circuits from Analog Devices. The series offers configurable voltage monitoring solutions for complex power architectures. The HGN variant specifically denotes the SSOP package option, while the #TRPBF suffix confirms lead-free tape-and-reel packaging compliant with RoHS standards. It serves as a dedicated solution for power integrity management in multi-supply environments.

Supervisors Replacement Considerations

The LTC2914HGN-2#PBF is a verified substitute offering identical electrical characteristics but in tube packaging instead of tape-and-reel. Both variants share the same functional pinout and performance specifications. Designers requiring reel packaging must ensure the TRPBF version is selected to avoid rework during assembly.
