LTC2911HTS8-5#TRMPBF

Supervisors Overview

The LTC2911HTS8-5#TRMPBF is a precision triple voltage monitor from Analog Devices Inc., housed in an SOT-23-8 package. It features three independent monitoring channels with fixed thresholds at 3.086V and adjustable thresholds via external resistors. The device includes a power-fail comparator, an open-drain output, and a fixed reset delay of 200 ms. It operates within a supply voltage range up to 6.5V and supports temperatures from -40°C to 85°C.

Supervisors Feature Summary

• Triple-channel voltage supervision with mixed fixed and adjustable threshold capabilities
• Integrated power-fail comparator for system status indication
• Open-drain output configuration for flexible logic interfacing
• Fixed 200 ms reset delay ensures stable power-up sequencing

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for microcontrollers and FPGAs
• Industrial control units requiring precise under-voltage detection

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lot traceability upon receipt. Check for discontinuance notices as the HTS8-5 variant may have limited availability compared to standard TSOP versions. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering.

Supervisors Selection Notes

Select this part when three distinct voltage rails require simultaneous supervision in a compact footprint. The adjustable thresholds allow customization for non-standard rail voltages, while the fixed 3.086V channel suits common logic levels. Consider the open-drain output requirement for pull-up resistor implementation. Verify that the 200 ms reset delay aligns with system startup timing constraints.

Supervisors Part Context

This component belongs to the LTC2911 family of precision supervisors. It shares functional similarities with the LTC2911ITS8 variants but differs in package type (HTS8 vs ITS8) and specific threshold configurations. The HTS8 designation indicates a thin small-outline package suitable for space-constrained PCB layouts.

Supervisors Replacement Considerations

Direct substitutes include other LTC2911 variants such as LTC2911ITS8-5#TRMPBF, provided package compatibility is verified. Cross-referencing with LTC2919 series may be necessary if negative voltage monitoring is required.
