LTC2945IUD#TRPBF

Power Supply Controllers, Monitors Overview

The LTC2945IUD#TRPBF is a rail-to-rail system monitor manufactured by Analog Devices Inc. It measures current, voltage, and power with high precision. The device operates within a supply voltage range of 2.7V to 80V. It includes an integrated shunt regulator designed for input supplies exceeding 80V, providing flexibility in input selection. This component is suitable for monitoring applications requiring comprehensive electrical parameter tracking.

Power Supply Controllers, Monitors Feature Summary

• Rail-to-rail system monitoring capability for current, voltage, and power
• Integrated shunt regulator supports input supplies above 80V
• Wide operating voltage range from 2.7V to 80V

Power Supply Controllers, Monitors Applications

• -48V harsh environment power monitoring
• Systems requiring tolerance for 200V transients via INTVCC shunt regulator
• General rail-to-rail power supervision

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix IUD#TRPBF against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with -48V systems if utilizing the shunt regulator feature for transient tolerance. Confirm availability status through authorized distributors as supply may be limited.

Power Supply Controllers, Monitors Selection Notes

Select this part when precise measurement of current, voltage, and power is required in a single component. The integrated shunt regulator makes it ideal for inputs exceeding 80V or where robust transient protection is needed. Consider the MSOP-12 package constraints and operating temperature range during design integration.

Power Supply Controllers, Monitors Part Context

This component belongs to the LTC2945 series of power monitors. It is distinct from other supervisory circuits like the LTC2934 or LTC2954 by its ability to measure multiple electrical parameters simultaneously rather than focusing solely on reset generation or push-button control.
