LTC2904IDDB#TRMPBF

Supervisors Overview

The LTC2904IDDB#TRMPBF is a dual-channel power management supervisor IC manufactured by Analog Devices Inc. It monitors two independent supply voltages and provides reset signals when thresholds are exceeded. The device features pin-selectable threshold settings, eliminating the need for external resistors to define trip points. It operates within an input voltage range of 1.7V to 5.5V and draws a typical quiescent current of 65µA. Packaged in an 8-lead DFN (3mm x 3mm) surface-mount package, it supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel supervision for monitoring two independent voltage rails simultaneously
• Pin-selectable threshold configuration simplifies design by removing external resistor dividers
• Low quiescent current consumption enhances efficiency in battery-powered applications

Supervisors Applications

• Portable electronic devices requiring multi-rail power monitoring
• Industrial control systems with multiple voltage domains
• Embedded systems needing precise reset signal generation for microcontrollers

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to procurement. Check for obsolescence notices or lifecycle changes as availability may vary. Ensure storage conditions meet specified humidity and temperature limits to prevent degradation. Validate packaging integrity upon receipt to avoid moisture sensitivity issues.

Supervisors Selection Notes

Select this component when dual-voltage supervision with fixed, pin-programmable thresholds is required. Consider the 65µA quiescent current for low-power designs. Evaluate the 8-lead DFN footprint against available PCB space. Compare performance against single-channel supervisors if only one rail requires monitoring. Verify that the selected threshold options match the specific supply voltages being monitored.

Supervisors Part Context

This part belongs to the LTC2904 series of precision dual-supply monitors. It complements other Analog Devices power management solutions by providing reliable reset generation for complex systems. The DFN package offers a compact solution for space-constrained designs compared to larger leaded packages.

Supervisors Replacement Considerations

Direct substitutes include other dual-channel supervisors from Analog Devices such as the LTC2903 or LTC2905, depending on threshold requirements and package compatibility. Cross-reference pinouts and electrical characteristics carefully before substitution.
