LTC2911ITS8-4#TRPBF

Supervisors Overview

The LTC2911ITS8-4#TRPBF is a low-power, high-accuracy triple supply monitor manufactured by Analog Devices Inc. It integrates three independent voltage supervisors and a power-fail comparator within an 8-pin TSOT-23 package. The device monitors fixed voltages of 3.3V and 1.2V, alongside one adjustable channel. It features a push-pull active-low reset output with selectable timeout durations determined by an external capacitor. Operating from a supply current of 10 µA, it supports a wide operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates three precision voltage monitoring channels for simultaneous multi-rail supervision
• Includes a dedicated power-fail comparator for system status indication
• Features selectable reset timeout periods via external capacitance
• Provides active-low push-pull reset output for direct microprocessor interfacing

Supervisors Applications

• Portable instrumentation requiring multi-voltage supervision
• Industrial automation control systems
• Embedded computing platforms with multiple power rails

Supervisors Procurement Notes

Verify the specific suffix code to confirm threshold voltages and package type. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check lead times as availability may vary by region. Ensure the selected variant matches your required reset polarity and timeout configuration before ordering.

Supervisors Selection Notes

Select this component when precise monitoring of three distinct voltage levels is required in a compact footprint. The adjustable channel allows flexibility for non-standard rail voltages. Consider the external capacitor requirement for setting reset delays. Verify that the 10 µA quiescent current meets your battery life or power budget constraints.

Supervisors Part Context

This part belongs to the LTC2911 series of triple supply monitors. Other variants in the family offer different fixed voltage thresholds or package options such as DFN-8. The ITS8 designation indicates the TSOT-23-8 thin plastic outline package. The #TRPBF suffix denotes tape-and-reel packaging with lead-free finish.

Supervisors Replacement Considerations

Direct substitutes include other LTC2911 variants with different threshold combinations, such as LTC2911ITS8-1#TRPBF or LTC2911ITS8-2#TRPBF, provided the voltage thresholds match the application requirements. Cross-family replacements require verification of pin compatibility and electrical specifications.
