LTC2911CDDB-5#TRMPBF

Supervisors Overview

The LTC2911CDDB-5#TRMPBF is a precision triple voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.6V to 6.5V and features an open-drain output. The device monitors three input voltages with fixed thresholds at 4.425V, 3.086V, and 2.93V. It includes a power-fail comparator with a reset delay time of 200ms. The component is housed in an 8-WFDFN package and supports industrial temperature operation.

Supervisors Feature Summary

• Provides precise monitoring for three independent voltage rails simultaneously
• Integrates a dedicated power-fail comparator for system status indication
• Features an open-drain reset output compatible with various logic families

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Voltage monitoring for microprocessor and FPGA core supplies
• Industrial control board power integrity verification

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when sourcing. Confirm the C grade denotes industrial temperature range suitability for your environment. Ensure the open-drain output configuration aligns with your pull-up resistor requirements. Cross-reference the datasheet for exact threshold tolerances before final integration.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage levels is required. The open-drain output necessitates an external pull-up resistor sized for your logic voltage. Consider the 200ms reset delay duration relative to your system startup sequence timing constraints. Verify that the 8-WFDFN footprint matches your PCB layout capabilities.

Supervisors Part Context

This part belongs to the LTC2911 series of precision supervisors. It shares functional similarities with other multi-channel monitors but offers specific fixed thresholds optimized for common rail voltages. The CDDB variant specifies the commercial/industrial temperature range and DFN package style compared to other housing options in the family.

Supervisors Replacement Considerations

LTC2911CDDB-5#TRPBF is a public confirmed substitute offering identical electrical specifications with standard tape and reel packaging.
