LTC2911HTS8-1#TRMPBF

Supervisors Overview

The LTC2911HTS8-1#TRMPBF is a precision three-channel voltage supervisor manufactured by Analog Devices Inc. It monitors multiple power rails and provides reset signals upon detecting out-of-range conditions. The device operates within a supply voltage range of up to 6.5 V and draws a typical quiescent current of 10 uA. It features an adjustable reset delay time of 200 ms and utilizes an open-drain output configuration. The component is housed in a compact SOT-23-8 surface-mount package, suitable for space-constrained designs requiring reliable power system supervision.

Supervisors Feature Summary

• Provides precise monitoring for three independent voltage inputs with configurable thresholds
• Features low quiescent current consumption for efficient power management
• Includes a programmable reset delay timer to prevent false triggering during transient events

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Portable instrumentation requiring low standby current
• Industrial automation control units

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited stock or restricted sales regions. Confirm the specific suffix #TRMPBF corresponds to the tape-and-reel packaging format required for automated assembly processes. Ensure compatibility with RoHS directives and check for any regional export controls or manufacturing changes prior to finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing circuits that require simultaneous monitoring of three distinct voltage levels within a single package. The open-drain output allows for flexible interfacing with various logic families. Consider the 200 ms reset delay duration to ensure stable operation during power-up sequences. Verify that the input voltage thresholds align with the specific rails being monitored in the target application design.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits from Analog Devices. It shares the TSOT-23-8 form factor with other members of the family but differs in threshold configurations and output types. The H-grade designation typically indicates extended temperature performance compared to standard industrial grades, ensuring reliability in demanding environments.

Supervisors Replacement Considerations

Direct substitutes include the LTC2911ITS8-1#TRMPBF for industrial temperature range applications. Other variants such as the LTC2911HTS8-2#TRMPBF offer different fixed threshold voltages. Ensure pinout compatibility and verify that the output drive capability meets the load requirements of the downstream circuitry before substitution.
