LTC2909IDDB-3.3#TRMPBF

Supervisors Overview

The LTC2909IDDB-3.3#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in power management systems. It features an open-drain output and supports adjustable reset timeouts. The device operates within a temperature range of -40°C to +85°C and utilizes an 8-WFDFN package with exposed pad. Key electrical parameters include a maximum supply voltage of 6 V, a quiescent current of 50 uA, and threshold voltages of 2.921V, adjustable, and adjustable.

Supervisors Feature Summary

• Provides precise supervision for three independent input voltage channels
• Features low-power operation suitable for battery-backed systems
• Offers configurable reset timeout durations via external components

Supervisors Applications

• Multi-rail system power monitoring
• Embedded controller supervision
• Industrial equipment voltage tracking

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when sourcing. Confirm the IDDB variant meets industrial temperature requirements. Ensure compatibility with 8-DFN footprints during PCB layout. Check for RoHS compliance documentation prior to integration.

Supervisors Selection Notes

Select this component when three-channel voltage monitoring is required in a compact surface-mount package. Consider the 50 uA quiescent current for efficiency-sensitive designs. Verify that the open-drain output logic levels match the receiving microcontroller or FPGA inputs.
