LTC2912CDDB-3#TRMPBF

Supervisors Overview

The LTC2912CDDB-3#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage rails. It operates within the LTC2912 series and utilizes an 8-WFDFN package with exposed pad for surface-mount installation. The device functions as an under-voltage and over-voltage monitor, providing open-drain or open-collector output signals to indicate fault conditions. It features adjustable or selectable threshold voltages and offers configurable reset timeout periods. The component supports a wide operating temperature range from -40°C to +125°C and draws a typical quiescent current of 40 µA, ensuring efficient power management in portable and battery-operated applications.

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape-and-reel packaging configuration when sourcing. Confirm availability status as distribution channels may report limited stock or special order requirements. Ensure compatibility with 8-WFDFN footprints during PCB layout finalization. Cross-reference datasheet revision levels to guarantee parameter consistency across production batches.

Supervisors Selection Notes

Select this variant when a single-channel supervisor with flexible threshold settings is required. Consider the 8-WFDFN package constraints for thermal dissipation and board space limitations. Evaluate the 40 µA quiescent current against system standby power budgets. Verify that the open-drain output interface aligns with the downstream logic level requirements of the monitored microcontroller or processor.
