LTC2938IMS#TRPBF

Power Supply Controllers, Monitors Overview

The LTC2938IMS#TRPBF is a configurable processor supervisor designed for systems requiring watchdog supervision. It monitors up to four supply voltages and features adjustable inputs with a nominal threshold of 0.5V. The device offers sixteen preset or adjustable voltage monitor combinations selectable via an external resistive divider, with thresholds accurate to ±1.5% over temperature. Reset and watchdog timeout periods are programmable using external capacitors. It operates within a supply voltage range of 1V to 6V, consumes a maximum supply current of 80µA, and supports manual reset functionality.

Power Supply Controllers, Monitors Feature Summary

• Configurable multi-supply monitoring with selectable voltage thresholds

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix IMS#TRPBF against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with required voltage thresholds and timing configurations before procurement. Cross-reference part status and availability through authorized distributors as supply conditions may vary.

Power Supply Controllers, Monitors Selection Notes

Select this component when multiple supply rails require simultaneous monitoring with customizable thresholds. The adjustable watchdog and reset timers provide flexibility for diverse system timing requirements. Verify that the 1V to 6V operating range and 80µA current consumption align with system power constraints and voltage levels.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2938/LTC2939 family of configurable supply monitors. These devices are designed for applications needing robust supervision of multiple voltage domains. The IMS variant indicates a specific surface-mount package configuration suitable for automated assembly processes in compact electronic designs.

Power Supply Controllers, Monitors Replacement Considerations

LTC2939CMS#PBF serves as a related alternative offering six monitored supplies instead of four. Verify pinout compatibility and functional equivalence regarding watchdog and reset configurations before substitution.
