LTC2911HDDB-1#TRMPBF

Supervisors Overview

The LTC2911HDDB-1#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply voltages in electronic systems. It features a single-channel configuration housed in an 8-WFDFN (3x2) package with an exposed pad, suitable for surface-mount assembly. The device provides a low-active reset output with adjustable or selectable thresholds and configurable reset timeouts. It operates within a temperature range of -40°C to 125°C TA. Key electrical parameters include an operating supply current of 10 µA and a voltage threshold that is adjustable or selectable depending on the specific variant configuration.

Supervisors Feature Summary

• Provides precise voltage supervision for critical power rails
• Features low quiescent current consumption for energy efficiency
• Offers configurable reset timing and threshold options
• Delivers reliable protection in compact surface-mount packaging

Supervisors Applications

• Portable instrumentation systems requiring low-power monitoring
• Industrial automation control units needing robust voltage supervision
• Embedded systems with strict space constraints for PMIC integration

Supervisors Procurement Notes

Verify the exact datasheet revision and ordering information directly from Analog Devices official documentation before procurement. Confirm that the specific suffix matches the required threshold and timeout configurations. Ensure compatibility with your system's voltage levels and thermal requirements. Check for any recent updates to the component's compliance status or recommended replacement parts. Always validate the supplier's authenticity to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a single-channel supervisor with low standby current is required. Consider the adjustable threshold feature if fixed voltage monitors do not match your design needs. The wide operating temperature range makes it suitable for harsh environments. Evaluate the small DFN footprint against available PCB real estate. Compare performance metrics with other supervisors in the LTC2911 family for optimal system integration.

Supervisors Part Context
