LTC2909IDDB-5#TRM

Supervisors Overview

The LTC2909IDDB-5#TRM is a precision triple/dual input under-voltage and over-voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 6 V and monitors three independent inputs for voltage excursions. The device features an open-drain reset output that asserts low when monitored voltages exceed specified thresholds. It includes a fixed 200 ms reset delay timer to ensure system stability during power transitions. The component is housed in an 8-pin DFN package and supports surface-mount installation.

Supervisors Feature Summary

• Monitors multiple power rails for under-voltage and over-voltage conditions simultaneously
• Provides active-low open-drain reset signal with configurable timeout
• Operates with low quiescent current suitable for battery-powered applications

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Processor supervisor circuits requiring precise voltage tracking
• Industrial control systems needing reliable fault detection

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as variations such as #TRMPBF or #TR may indicate differences in packaging or compliance status. Confirm availability through authorized distributors, as some variants may be discontinued or subject to allocation. Ensure the part number matches the specific threshold and package requirements for your design.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three voltage rails is required in a compact footprint. Consider the fixed 200 ms reset delay and open-drain output compatibility with your microcontroller or logic interface. Evaluate the operating temperature range and accuracy specifications against system requirements before integration.

Supervisors Part Context

This part belongs to the LTC2909 series of precision voltage monitors from Analog Devices. The series offers various threshold options and package configurations to suit different multi-supervisory needs. It is designed for applications requiring high accuracy and low power consumption in space-constrained environments.

Supervisors Replacement Considerations

Check Analog Devices datasheets for direct pin-compatible alternatives within the LTC2909 family. Verify if other suffixes like #TRMPBF offer identical electrical characteristics. Cross-reference with similar supervisory ICs only if functional equivalence is confirmed by manufacturer data.
