LTC1326IS8#TRPBF

Supervisors Overview

The LTC1326IS8#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in embedded systems. It features three independent monitor inputs with selectable thresholds of 3.3 V, 5 V, or adjustable settings. The device operates within a supply voltage range of 1 V to 7 V and maintains an accuracy of 0.75%. It draws a typical quiescent current of 40 uA and includes a fixed reset delay time of 200 ms. The component supports active high, active low, and open drain output configurations and incorporates power fail detection capabilities.

Supervisors Feature Summary

• Provides simultaneous supervision of three distinct input voltages
• Offers flexible threshold selection including fixed and adjustable options
• Supports multiple output logic states for system integration flexibility

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Multi-rail power management circuits

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure the part number matches the required operating temperature range and output configuration. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance status and any recent design changes before procurement.

Supervisors Selection Notes

Select this component when multi-voltage supervision is required in space-constrained designs. Consider the 40 uA quiescent current for battery-operated applications. Verify that the 200 ms reset delay aligns with system startup requirements. Ensure the chosen threshold options match the target voltage rails without external resistor networks if using fixed variants.

Supervisors Part Context
