LTC2931HF#PBF

Power Supply Controllers, Monitors Overview

The LTC2931HF#PBF is a six-channel power supply monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 1V to 7V and supports an operating temperature range from -40°C to +125°C. The device utilizes a factory-set reset threshold to monitor voltages between 1.1V and 5V, with specific threshold options including 1.5V, 1.8V, 2.5V, 3V, 3.3V, 5V, or adjustable settings. It features a reset delay time of 3 ms and is housed in a 20-TSSOP package.

Power Supply Controllers, Monitors Feature Summary

• Provides robust power-system supervision for safety-critical automotive applications
• Monitors up to six independent power supply rails simultaneously
• Utilizes factory-set reset thresholds for simplified design integration

Power Supply Controllers, Monitors Applications

• Safety-critical automotive systems requiring multi-rail supervision
• Industrial equipment monitoring multiple voltage levels
• Embedded systems needing reliable power fault detection

Power Supply Controllers, Monitors Procurement Notes

Verify the exact threshold configuration (e.g., 1.5V, 1.8V, etc.) matches your system requirements, as this variant uses fixed factory-set values. Confirm the 20-TSSOP package compatibility with your PCB footprint. Ensure the 3ms reset delay aligns with your system's startup timing constraints. Check RoHS compliance details if required for your region. Validate that the 1V to 7V supply range covers your highest monitored rail.

Power Supply Controllers, Monitors Selection Notes

Select this component when simultaneous monitoring of six distinct power rails is necessary within a compact surface-mount package. The wide operating temperature range makes it suitable for harsh environments. Consider the fixed threshold options against adjustable alternatives if flexibility is not required. The 3ms delay provides fast response without excessive noise sensitivity. Ensure the input voltage range accommodates all monitored supplies up to 5V.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2931 series of power supply monitors designed for high-reliability applications. It integrates multiple supervisory channels into a single IC, reducing board space compared to discrete solutions. The device is optimized for automotive and industrial sectors where failure detection is critical. It complements other PMIC offerings from Analog Devices focused on system protection.
