LTC2901-3IGN#TRPBF

Supervisors Overview

The LTC2901-3IGN#TRPBF is a quad power supply monitor manufactured by Analog Devices Inc. It features four independent voltage monitoring channels with adjustable reset thresholds and a watchdog timer. The device operates within a supply voltage range of 2.7V to 5.5V and consumes low quiescent current. It provides active-low reset outputs with selectable timeout periods and is housed in a 16-lead SSOP package.

Supervisors Feature Summary

• Four independent voltage monitoring channels for comprehensive system supervision
• Adjustable reset threshold voltages via external resistor dividers
• Integrated watchdog timer with programmable timeout intervals
• Active-low reset output with configurable delay times

Supervisors Applications

• Multi-rail power supply systems requiring independent voltage monitoring
• Industrial control units with multiple logic voltage domains
• Telecommunications equipment power management subsystems
• Embedded systems needing reliable brown-out detection

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging configuration. Confirm the -3 variant corresponds to the correct threshold combination set required for your design. Check current availability status as distribution may vary by region. Ensure compatibility with your board's thermal requirements for the SSOP package.

Supervisors Selection Notes

Select this component when designing systems with up to four distinct voltage rails that require simultaneous monitoring. Consider the available threshold combinations for the -3 variant against your specific trip points. Evaluate the need for watchdog functionality versus simple voltage supervision. Compare pinout compatibility if replacing existing supervisor ICs in legacy designs.

Supervisors Part Context

This part belongs to the LTC2901 family of programmable multi-supervisor circuits. It shares core architecture with other variants like the LTC2901-1 and LTC2901-2, differing primarily in factory-programmed threshold combinations. The family is designed for cost-effective power management in space-constrained applications requiring precise voltage supervision.

Supervisors Replacement Considerations

Direct substitutes include other LTC2901 variants such as LTC2901-1IGN#TRPBF or LTC2901-2IGN#TRPBF, provided their preset threshold combinations match your circuit requirements. Verify pin-to-pin compatibility before substitution.
