LTC2911HTS8-3

Supervisors Overview

The LTC2911HTS8-3 is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring three independent voltage rails. It features an integrated power-fail comparator and adjustable reset timeout, housed in a compact TSOT-23-8 package. The device operates within a temperature range of -40°C to 85°C and draws a typical supply current of 10 µA. Key electrical parameters include fixed thresholds at 3.086V and 4.675V, with a third adjustable threshold channel. It provides a push-pull/totem-pole output with active-low reset functionality.

Supervisors Feature Summary

• Monitors three independent voltage channels with dedicated power-fail comparison capabilities
• Features an adjustable reset timeout period for flexible system timing requirements
• Delivers active-low reset signals via a push-pull output stage

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Voltage monitoring for microprocessor and FPGA boards
• Industrial control unit power integrity verification

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required threshold configuration. Request official datasheets and test reports to ensure compliance with RoHS standards. Validate package markings against manufacturer specifications to prevent counterfeit infiltration during acquisition.

Supervisors Selection Notes

Select this component when precise monitoring of three distinct voltage levels is required alongside power-fail detection. Consider the TSOT-23-8 footprint for space-constrained designs. Ensure the fixed threshold values align with target rail voltages. Evaluate the adjustable timeout feature against system startup stability requirements before finalizing the design.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits from Analog Devices. It complements other variants like the ITS8-1 and HTS8-5 by offering specific threshold combinations. The series targets applications requiring reliable voltage monitoring in compact surface-mount packages for modern electronic equipment.

Supervisors Replacement Considerations

Direct substitutes include LTC2911ITS8-1#TRMPBF and LTC2911HTS8-5#TRPBF. Verify that alternative part numbers match the required voltage thresholds and package type. Cross-reference pinouts and electrical characteristics to ensure functional compatibility in existing designs.
