LTC2911CDDB-2#TRMPBF

Supervisors Overview

The LTC2911CDDB-2#TRMPBF is a precision triple supply monitor manufactured by Analog Devices Inc. It features three independent voltage monitoring channels with a dedicated power-fail comparator. The device operates within a maximum supply voltage of 6.5 V and draws minimal quiescent current. It provides an open-drain output type and includes a fixed reset delay time of 200 ms. The component is housed in an SOT-23-8 package, suitable for surface mount installation.

Supervisors Feature Summary

• Provides precise monitoring for three separate input voltages simultaneously
• Integrates a dedicated power-fail comparator for system status indication
• Features a fixed 200 ms reset delay to ensure stable power-up sequencing

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Voltage monitoring for industrial control units
• Power management in automotive electronic modules

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging configuration. Confirm the CDDB variant corresponds to the commercial temperature range specifications. Ensure compatibility with the target PCB footprint for the SOT-23-8 package before finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is required alongside power-fail detection. The fixed 200 ms reset delay suits applications where predictable startup timing is critical without external capacitor tuning. Consider the open-drain output capability for interfacing with various logic levels.

Supervisors Part Context

This part belongs to the LTC2911 series of low-power, high-accuracy triple supply monitors. The series is designed for applications requiring compact solutions for multi-voltage supervision. The CDDB designation specifies the commercial grade temperature range and the specific DFN/SOT-23 package style used in this iteration.

Supervisors Replacement Considerations

LTC2911ITS8-2#TRMPBF offers similar functionality with potentially different temperature ratings or pin configurations. Verify electrical parameters and package dimensions against the original design requirements before substitution.
