LTC2918IDDB-B1#TRMPBF

Supervisors Overview

The LTC2918IDDB-B1#TRMPBF is a voltage supervisor integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7V to 5.5V and features an adjustable reset threshold with a typical accuracy of ±0.6%. The device provides one monitored input channel and utilizes a push-pull output configuration for the reset signal. It incorporates an adjustable reset delay timer ranging from 1ms to 10s, ensuring reliable system recovery. The component functions across an industrial temperature range of -40°C to +85°C and is housed in a compact 10-DFN package.

Supervisors Feature Summary

• Adjustable reset threshold allows precise monitoring of various voltage rails
• Configurable reset delay timer prevents false triggers during power-up transients
• Push-pull output driver supports direct interfacing with logic inputs

Supervisors Applications

• Portable battery-powered equipment requiring low quiescent current
• Industrial control systems needing robust voltage supervision
• Embedded computing platforms with multiple power domains

Supervisors Procurement Notes

Verify the specific suffix B1 against official Analog Devices documentation to confirm the exact reset threshold characteristics and pinout configuration. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm availability status through authorized distributors as supply levels may fluctuate. Cross-reference the datasheet revision date to ensure all electrical specifications align with current design standards.

Supervisors Selection Notes

Select this component when a single-channel supervisor with adjustable timing and threshold is required. Compare the adjustable delay range against system startup sequences to ensure adequate hold-off time. Evaluate the push-pull output capability against load requirements compared to open-drain alternatives. Consider the DFN package size constraints relative to available board space and thermal dissipation needs.
