LTC2931HF

Power Supply Controllers, Monitors Overview

The LTC2931HF is a configurable six-supply monitor manufactured by Analog Devices Inc. It provides precise threshold detection across six monitored inputs with typical hysteresis of ±0.5%. The device features adjustable reset and watchdog timers, supporting manual reset functionality. It operates within a supply voltage range of 1V to 7V and is housed in a 20-TSSOP package. This supervisory circuit is designed for reliable brownout detection in multi-rail power systems.

Power Supply Controllers, Monitors Feature Summary

• Configurable monitoring for up to six independent power supplies
• Adjustable reset and watchdog timer intervals
• Precise threshold detection with low hysteresis for stable operation

Power Supply Controllers, Monitors Applications

• Multi-rail power supply monitoring in industrial equipment
• Brownout detection in embedded systems
• System supervision in telecommunications infrastructure

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix (e.g., #PBF) against the manufacturer's current product status. Confirm RoHS compliance details directly from the official datasheet. Check for limited distribution or obsolete status as availability may vary by region and factory order constraints.

Power Supply Controllers, Monitors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required. Ensure the input voltage range aligns with the system's supply levels. Verify that the package type fits the PCB layout constraints. Consider the need for adjustable timing features versus fixed thresholds offered by other family members.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC293x series of power supply monitors from Analog Devices. It shares functional similarities with models like the LTC2935 but offers a different pin count and configuration options suited for six-channel applications. The series focuses on low-power, high-accuracy supervision for complex electronic designs.

Power Supply Controllers, Monitors Replacement Considerations

Direct substitutes include other parts within the LTC293x family such as the LTC2931HF#TRPBF for tape-and-reel packaging. Cross-reference pinouts and electrical characteristics carefully before replacing.
