LTC2904IDDB#TRPBF

Supervisors Overview

The LTC2904IDDB#TRPBF is a precision dual supply voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7V to 36V and draws a typical quiescent current of 850nA. The device features two independent voltage monitoring channels with pin-selectable thresholds, eliminating the need for external resistors. It provides an active-low reset output with a fixed 200ms timeout delay. Packaged in an 8-lead DFN (3x2mm) surface-mount case, it supports industrial temperature ranges.

Supervisors Feature Summary

• Pin-selectable threshold voltages remove the requirement for external resistor dividers
• Ultra-low 850nA supply current enables extended battery life in portable applications
• Dual-channel architecture monitors both positive and negative supply rails simultaneously

Supervisors Applications

• Portable electronic devices requiring low-power supply supervision
• Battery-operated systems needing precise voltage tracking
• Industrial equipment monitoring dual power rail integrity

Supervisors Procurement Notes

Verify the specific suffix IDDB against official Analog Devices documentation to confirm package type and thermal characteristics. Confirm RoHS compliance status through the manufacturer's latest material declaration. Ensure the ordering part number matches the exact pin configuration required for your PCB layout design.

Supervisors Selection Notes

Select this component when dual-rail monitoring is required without external biasing networks. The pin-selectable feature simplifies BOM management compared to adjustable supervisors. Consider the 850nA quiescent current for strict power budget constraints. Verify that the 200ms reset delay aligns with system startup timing requirements.

Supervisors Part Context

This component belongs to the LTC2904 family of nano-current voltage monitors. It shares the core monitoring architecture with other members like the LTC2908 but differs in channel count and threshold selection methods. The DFN package offers a compact footprint suitable for space-constrained modern electronics designs.
