LTC699CS8#PBF

Supervisors Overview

The LTC699CS8#PBF is a single-channel voltage supervisor manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It provides simple reset and power-on-reset functionality with an open-drain or open-collector output. The device monitors a single input voltage against a fixed threshold of 4.65V, triggering a low-active reset signal when the supply drops below this level. It features a minimum reset timeout of 140ms to ensure stable system initialization. Operating within a temperature range of 0°C to +70°C, it is designed for reliable supervision in commercial electronic applications requiring precise voltage monitoring.

Supervisors Feature Summary

• Provides automatic power-on-reset and undervoltage detection for microprocessor systems
• Features an open-drain or open-collector output compatible with various logic families
• Includes a guaranteed minimum reset timeout period to prevent premature system activation

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-powered equipment voltage monitoring
• Industrial control system reset circuits

Supervisors Procurement Notes

Verify the exact part number suffix and manufacturer lot codes upon receipt. Confirm RoHS compliance status through official documentation as specifications may evolve. Ensure storage conditions meet moisture sensitivity level requirements before soldering. Cross-reference ordering information with the current Analog Devices datasheet to confirm availability and packaging details.

Supervisors Selection Notes

Select this component when a fixed 4.65V threshold is appropriate for the target supply rail. Consider the 8-SOIC package constraints for PCB layout and thermal management. Evaluate if the open-drain output interface meets the downstream logic requirements without additional pull-up components. Verify that the operating temperature range aligns with the intended environmental conditions.

Supervisors Part Context

This device belongs to the LTC699 series of supervisory circuits from Analog Devices. It serves as a fundamental building block for ensuring system stability during power transitions. The series offers various threshold options and package configurations to suit different voltage monitoring needs across consumer and industrial electronics markets.

Supervisors Replacement Considerations

Consult Analog Devices documentation for direct pin-compatible alternatives within the same family. Verify that any substitute maintains the 4.65V threshold and 8-SOIC footprint. Ensure functional equivalence in reset timing and output drive capability before implementation.
