LTC2901-4IGN#PBF

Supervisors Overview

The LTC2901-4IGN#PBF is a programmable quad supply monitor manufactured by Analog Devices Inc. It operates within a voltage range of 1.6 V to 5.5 V and features four independent voltage monitoring channels with adjustable thresholds. The device provides open-drain reset outputs and supports configurable watchdog timers. It is housed in a 16-lead SSOP package and is rated for operation from -40°C to +85°C.

Supervisors Feature Summary

• Four independent voltage monitoring channels with adjustable threshold voltages
• Configurable watchdog timer functionality for system reliability
• Open-drain reset output compatible with various logic levels

Supervisors Applications

• Multi-rail power supply supervision in industrial systems
• Battery backup monitoring in embedded controllers
• Voltage supervision in communication equipment

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status. Confirm the -4IGN designation corresponds to the industrial temperature range (-40°C to +85°C) and SSOP-16 package. Cross-reference the datasheet for exact threshold adjustment resistor values and watchdog timeout configurations to ensure compatibility with target circuit requirements.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision with customizable reset timing. The integrated watchdog feature reduces external component count compared to discrete solutions. Ensure the input voltage range aligns with the monitored rails and that the open-drain output can interface correctly with the downstream processor or microcontroller reset line.

Supervisors Part Context

This part belongs to the LTC2901 family of programmable supply monitors. It shares architectural similarities with variants like the LTC2901-1, differing primarily in threshold configuration options and package availability. The series is designed for applications requiring precise voltage supervision without complex external programming interfaces.
