LTC2914IGN-2#PBF

Supervisors Overview

The LTC2914IGN-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 adjustable threshold mechanism to define trip points for each channel. It provides open-drain output signals to indicate fault states. The component operates within a supply voltage range up to 7V and maintains accuracy within 1.5%. It includes a reset delay time of 8.5 ms and functions reliably across an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors four independent voltage inputs for under-voltage and over-voltage events
• Features adjustable thresholds for customizable trip point configuration
• Provides open-drain outputs for fault indication signaling
• Operates with low quiescent current consumption

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Industrial control board voltage monitoring
• Telecommunications equipment power integrity verification
• Automotive electronic unit voltage tracking

Supervisors Procurement Notes

Verify the specific suffix IGN-2 against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels not exceeding 7V. Confirm that the open-drain output architecture aligns with downstream logic requirements. Check for any recent product change notifications affecting pinout or electrical characteristics before finalizing procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required. The adjustable threshold feature allows flexibility for non-standard voltage levels. Consider the DFN-16 package constraints for PCB layout. Evaluate the 1.5% accuracy specification against system tolerance requirements. Verify that the absence of manual reset and watchdog timer meets the application's safety logic design.

Supervisors Part Context

This part belongs to the LTC2914 series of supervisory circuits from Analog Devices. It is categorized under Power Management ICs (PMIC). The device is specifically engineered for applications requiring robust voltage monitoring without complex digital interfaces. It serves as a critical component for ensuring system stability by detecting abnormal power conditions early.

Supervisors Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully. Generic equivalents may lack the precise 1.5% accuracy or multi-channel capability.
