LTC2911CTS8-5#TRMPBF

Supervisors Overview

The LTC2911CTS8-5#TRMPBF is a precision triple voltage supervisor manufactured by Analog Devices Inc., housed in an 8-pin TSOT-23 package. It monitors three independent supply rails with fixed thresholds of 4.387V, 2.625V, and 2.047V. The device features a push-pull active-low reset output and an open-drain power-fail indicator. It operates within a supply voltage range of 1.2V to 5.5V and supports adjustable or selectable reset timeouts. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simultaneous supervision for three distinct voltage rails using dedicated inputs
• Generates a deterministic active-low reset signal via a push-pull output stage
• Includes an open-drain power-fail comparator for early warning detection
• Supports configurable reset delay timing through external components

Supervisors Applications

• Multi-rail embedded system power management
• Industrial control unit voltage monitoring
• Telecommunications equipment power sequencing
• Portable electronic device battery and rail supervision

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm threshold configurations. Ensure the ordering part number matches the required voltage levels and package type. Confirm RoHS compliance status and moisture sensitivity classification prior to integration into production workflows.

Supervisors Selection Notes

Select this component when precise monitoring of three separate voltage lines is required in a compact surface-mount footprint. Consider the push-pull reset capability for driving downstream logic directly. Evaluate the operating temperature range and supply voltage limits against the target application environment requirements.

Supervisors Part Context

This part belongs to the LTC2911 family of multi-supply supervisors from Analog Devices. These devices are designed for applications requiring reliable power integrity monitoring in space-constrained environments. The series offers various threshold combinations and package options to suit diverse system architectures.

Supervisors Replacement Considerations

Consult official cross-reference data for verified substitutes. Ensure any alternative maintains identical pinout compatibility and electrical specifications.
