LTC2901-2IGN#TRPBF

Supervisors Overview

The LTC2901-2IGN#TRPBF is a programmable quad supply monitor manufactured by Analog Devices Inc. It integrates four voltage supervisors with adjustable reset thresholds and watchdog timers in a 16-lead SSOP package. The device supports active-low or push-pull outputs and operates within an industrial temperature range of -40°C to +85°C. It features 16 selectable threshold combinations for monitoring multiple power rails, ensuring system reliability through configurable supervision logic.

Supervisors Feature Summary

• Integrates four independent voltage monitors with programmable reset thresholds
• Includes built-in watchdog timer functionality for processor protection
• Offers flexible output configurations including active-low and push-pull options

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Processor supervisor circuits requiring watchdog capabilities
• Industrial control systems monitoring critical voltage levels

Supervisors Procurement Notes

Verify the exact suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the -2 variant matches specific threshold requirements against the official datasheet. Ensure compatibility with the 16-SSOP footprint during PCB layout review. Cross-reference the manufacturer part number directly with Analog Devices documentation to avoid substitution errors.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of four distinct voltage rails. Consider the integrated watchdog feature if processor lockup protection is necessary. Evaluate the available threshold combinations to ensure coverage of all required supply voltages without external resistor networks. Verify package availability aligns with automated assembly requirements.

Supervisors Part Context

This part belongs to the LTC2901 family of quad supply monitors. It shares core architecture with variants like LTC2901-1IGN but differs in specific threshold programming options. The family provides a consolidated solution for complex power management supervision tasks in space-constrained applications.

Supervisors Replacement Considerations

LTC2901-1IGN#TRPBF serves as a functional alternative within the same series. Verify threshold configuration compatibility before substitution. Other family members may offer different pinouts or output types.
