LTC2912CDDB-1#TRMPBF

Supervisors Overview

The LTC2912CDDB-1#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage rails. It operates within a supply current of 40 uA and utilizes an 8-DFN package with surface mount technology. The device provides under-voltage and over-voltage monitoring capabilities, featuring an open-drain or open-collector output that asserts a low-active reset signal. It supports adjustable or selectable reset timeouts and offers configurable voltage thresholds to accommodate various system requirements.

Supervisors Feature Summary

• Provides comprehensive under-voltage and over-voltage monitoring for critical power rails
• Features an open-drain or open-collector output for flexible interface compatibility
• Supports adjustable or selectable reset timeout durations for customized system sequencing
• Operates with low quiescent current consumption to enhance energy efficiency

Supervisors Applications

• Single-rail power supply supervision in embedded systems
• Under-voltage and over-voltage protection in industrial control units
• Reset generation for microprocessors requiring configurable timing delays
