LTC2914CDHC-2#PBF

Supervisors Overview

The LTC2914CDHC-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. 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 supports a reset delay time of 8.5 ms and functions reliably across a temperature range from -40°C to +125°C, consuming only 70 µA of quiescent current.

Supervisors Feature Summary

• Monitors four independent voltage inputs for both under-voltage and over-voltage events
• Provides open-drain output signaling for fault detection without requiring manual reset
• 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 embedded computing systems
• Fault detection in communication infrastructure hardware

Supervisors Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS adherence before procurement. Confirm the DFN-16 package dimensions match your PCB footprint requirements. Ensure the 7 V maximum supply voltage aligns with your system's rail specifications. Check availability status as distribution channels may indicate limited stock or regional restrictions.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required. The adjustable threshold capability allows customization for various logic levels. Consider the 1.5% accuracy specification for precision applications. The wide operating temperature range makes it suitable for harsh environments where standard commercial grade parts may fail.

Supervisors Part Context

This part belongs to the LTC2914 series of supervisory circuits from Analog Devices. It is categorized under PMIC - Power Management ICs. The device is distinct from other series members by its specific four-channel monitoring architecture and open-drain output type, differentiating it from single-channel or push-pull output variants.

Supervisors Replacement Considerations

Direct substitutes include other LTC2914 variants with compatible pinouts and electrical characteristics. Verify that any replacement maintains the four-input monitoring capability and open-drain output structure. Ensure the replacement part supports the same DFN-16 package and operating temperature range.
