LTC2905CTS8#TRPBF

Supervisors Overview

The LTC2905CTS8#TRPBF is a precision dual supply voltage monitor manufactured by Analog Devices Inc. It features two independent monitoring channels with pin-selectable threshold voltages, eliminating the need for external resistors. The device operates within a supply voltage range of 1.7V to 6V and consumes low quiescent current. It provides open-drain reset outputs with configurable polarity and includes a fixed reset delay time of 140ms minimum. Packaged in an 8-lead DFN (3x2mm) surface-mount package, it supports industrial temperature ranges.

Supervisors Feature Summary

• Pin-selectable threshold voltages for both monitoring channels
• Dual independent voltage supervision capabilities
• Configurable active-low or active-high reset output polarity
• Low power consumption suitable for battery-operated systems

Supervisors Applications

• Portable electronic devices requiring precise voltage monitoring
• Battery-powered equipment with multiple voltage rails
• Industrial control systems needing reliable supervisor circuits
• Communication infrastructure power management

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm lot traceability and RoHS compliance status prior to integration. Check for obsolescence notices as availability may be restricted. Ensure storage conditions meet moisture sensitivity level requirements for lead-free packages.

Supervisors Selection Notes

Select this component when dual-channel supervision with fixed thresholds is required without external resistor networks. Compare against LTC2904 for single-supply applications or LTC2906 if one adjustable input is needed. Evaluate quiescent current requirements against system power budgets. Verify package compatibility with PCB footprint designs.

Supervisors Part Context

Part of the LTC290x family of precision supervisors from Analog Devices. Shares architectural similarities with LTC2904 and LTC2906 but offers distinct threshold selection options. Designed for compact designs where space and accuracy are critical constraints in power management architectures.

Supervisors Replacement Considerations

LTC2904CTS8#TRPBF offers similar functionality with different threshold configurations. LTC2906CTS8#TRPBF provides one adjustable input option. Verify electrical parameters and pinout compatibility before substitution.
