LM3702XCTP-308/NOPB

Supervisors Overview

The LM3702XCTP-308/NOPB is a single-channel voltage supervisor integrated circuit manufactured by Texas Instruments. It features a fixed threshold voltage of 3.08 V for monitoring power supply integrity. The device utilizes a 9-pin USMD package and supports surface mount installation. It provides an active low, open-drain reset output with a manual reset capability. The component operates within a temperature range of -40°C to +85°C and has a maximum supply voltage of 5.5 V.

Supervisors Feature Summary

• Single-channel voltage supervision with a fixed 3.08 V threshold
• Manual reset functionality for system control
• Active low, open-drain reset output configuration

Supervisors Applications

• Microprocessor supervisory circuits
• Power-on reset generation
• Battery-powered system monitoring

Supervisors Procurement Notes

This specific part number is listed as obsolete and no longer manufactured by Texas Instruments. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the condition and origin of available units, as new production is unavailable. Cross-referencing with current replacement options is recommended before finalizing any acquisition plans.

Supervisors Selection Notes

Designers requiring this specific 3.08 V threshold in a USMD package should note that direct replacement is not possible due to obsolescence. Selection criteria must shift towards evaluating substitute components with similar electrical characteristics, such as threshold voltage and output type. Compatibility with existing PCB footprints and system timing requirements should be prioritized when choosing an alternative supervisor IC.

Supervisors Part Context

The LM3702 series belongs to Texas Instruments' lineup of voltage supervisors designed for reliable system monitoring. This variant specifically targets applications needing precise voltage tracking with manual intervention capabilities. The USMD package offers a compact solution for space-constrained designs. As an older component, it represents a previous generation of supervisor technology now being phased out in favor of newer, more integrated solutions.

Supervisors Replacement Considerations

Public confirmed substitutes include the MAX706TCUA+. Engineers should evaluate this alternative for pin compatibility and electrical performance matching against the original specifications.
