LTC2914HDHC-2#PBF

Supervisors Overview

The LTC2914HDHC-2#PBF 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 operates within a supply voltage range up to 7 V. It exhibits a reset delay time of 8.5 ms and maintains an accuracy of 1.5%. The component functions reliably across an extended temperature range from -40°C to +125°C, consuming a typical operating supply current of 70 µA.

Supervisors Feature Summary

• Supports simultaneous monitoring of four distinct voltage inputs for both under-voltage and over-voltage events
• Features adjustable threshold voltages to accommodate various system requirements
• Provides open-drain output signaling for flexible interface integration
• Operates with low power consumption suitable for battery-backed or energy-efficient systems

Supervisors Applications

• Multi-rail power supply supervision in industrial equipment
• Voltage monitoring in telecommunications infrastructure
• System integrity checks in automotive electronics
• Backup power management in embedded computing systems

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the DFN-16 package dimensions match your PCB footprint design. Ensure the adjustable threshold capability aligns with your target voltage levels. Check for any regional distribution restrictions as availability may vary by location. Validate that the 8.5 ms reset delay meets your system's timing requirements.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision is required without manual reset functionality. Consider the 70 µA quiescent current for power-sensitive designs. The adjustable thresholds offer flexibility compared to fixed-threshold alternatives. Ensure the 7 V maximum supply voltage covers your highest rail. The wide operating temperature range supports harsh environment deployments.
