LTC2901-2IGN#PBF

Supervisors Overview

The LTC2901-2IGN#PBF is a programmable quad supply monitor housed in a 16-pin SSOP package. It features four independent voltage monitoring channels with adjustable thresholds and an integrated watchdog timer. The device provides active-low reset outputs and supports manual reset input functionality. It operates within a temperature range of -40°C to +85°C and includes delay timers for reset assertion.

Supervisors Feature Summary

• Programmable quad voltage monitoring with adjustable threshold selection
• Integrated watchdog timer with configurable timeout intervals
• Active-low push-pull or open-drain reset output options
• Manual reset input capability for system control

Supervisors Applications

• Processor supervisor circuits in embedded systems
• Multi-rail power supply monitoring in industrial equipment
• Watchdog timer implementation for fault detection
• Voltage threshold monitoring in communication modules

Supervisors Procurement Notes

Verify the exact suffix #PBF confirms lead-free compliance and tube packaging. Confirm the -2 variant matches required threshold combinations. Check datasheet for specific reset delay timing requirements. Ensure SSOP-16 footprint compatibility with PCB layout. Validate operating temperature range against environmental specifications.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision. Choose based on available threshold combinations from the datasheet table. Consider the watchdog timer needs for system reliability. Verify interface compatibility with microcontroller reset lines. Evaluate package size constraints for the target application board.

Supervisors Part Context

This part belongs to the LTC2901 family of quad supply monitors. It shares core architecture with variants like LTC2901-1 and LTC2901-3, differing primarily in threshold configurations. The IGN suffix indicates industrial temperature grade and SSOP packaging. Analog Devices designs this series for robust power management supervision.

Supervisors Replacement Considerations

LTC2901-1IGN#PBF offers similar functionality with different threshold settings. LTC2901-3IGN#PBF provides alternative voltage monitoring combinations. Cross-reference datasheet tables for compatible threshold values before substitution.
