LTC2914HDHC-2#TRPBF

Supervisors Overview

The LTC2914HDHC-2#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails. It features four independent inputs capable of detecting both under-voltage and over-voltage conditions with adjustable thresholds. The device utilizes an open-drain output configuration and provides a reset delay time of 8.5 ms. It operates within a supply voltage range up to 7 V and maintains an accuracy of 1.5%. The component is housed in a DFN-16 package, supports surface mount installation, and functions reliably across a temperature range of -40°C to +125°C while consuming 70 µA of operating current.

Supervisors Feature Summary

• Monitors four independent voltage inputs for under-voltage and over-voltage events
• Features adjustable threshold voltages for flexible system configuration
• Provides open-drain output signaling for reset or alert functions
• Operates with low power consumption suitable for battery-backed systems

Supervisors Applications

• Multi-rail power supply supervision in industrial equipment
• Voltage monitoring in embedded computing platforms
• System integrity checks in automotive electronics
• Power management units requiring precise threshold detection

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm that the HDHC variant corresponds to the DFN-16 package type required for your PCB layout. Ensure compatibility with the 7 V maximum supply voltage and 1.5% accuracy specifications for your application requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability and lead times through authorized distributors.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous monitoring with adjustable thresholds. The DFN-16 package offers a compact footprint for space-constrained designs. Consider the 8.5 ms reset delay and open-drain output characteristics when interfacing with downstream logic. Verify that the operating temperature range meets environmental demands and that the 70 µA quiescent current aligns with power budget constraints.

Supervisors Part Context

This part belongs to the LTC2914 series of supervisory circuits from Analog Devices. It is distinct from other variants such as the LTC2912 or LTC2934 which offer different channel counts or feature sets. The HDHC designation specifies the thermal pad DFN-16 package, while the #TRPBF suffix denotes the reel packaging format. It serves as a dedicated voltage monitor rather than a regulator or controller.
