LTC2912IDDB-2#TRPBF

Supervisors Overview

The LTC2912IDDB-2#TRPBF is a single-channel under-voltage and over-voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7V to 36V and draws a typical quiescent current of 40µA. The device features an open-drain reset output with a fixed 8.5ms timeout delay. It is housed in an 8-pin DFN package and supports operation temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Provides continuous monitoring for single power rails against under-voltage and over-voltage conditions
• Features low operating current consumption suitable for battery-powered applications
• Includes a fixed timeout delay to ensure stable reset signal generation during power transitions

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Industrial control systems needing reliable voltage supervision
• Communication equipment monitoring critical power rails

Supervisors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the IDDB variant corresponds to the industrial temperature range specifications. Ensure compatibility with the target board's footprint for the DFN-8 package. Cross-reference the manufacturer datasheet for exact pinout definitions before integration.

Supervisors Selection Notes

Select this component when a single-channel supervisor with wide input voltage capability is required. The 40µA quiescent current makes it suitable for energy-sensitive designs. Verify that the fixed 8.5ms delay meets system timing requirements. Consider the DFN-8 package size constraints relative to available PCB real estate.

Supervisors Part Context

This part belongs to the LTC2912 series of voltage monitors designed for simple, cost-effective power supervision. It complements other PMIC solutions by providing dedicated fault detection without complex configuration interfaces. The series supports various packages including DFN and SOT variants for different form factors.

Supervisors Replacement Considerations

LTC2912HDDB-2#TRPBF offers similar functionality but may differ in temperature grade or package tolerance. Verify electrical parameters match exactly before substitution.
