LM3704XCBPX-308

Supervisors Overview

The LM3704XCBPX-308 is a microprocessor supervisory circuit featuring a single voltage monitoring threshold set at 3.08V. It provides an active low reset signal with a push-pull, totem pole output configuration. The device includes a minimum reset timeout of 140ms to ensure stable power-up sequences. It operates within a junction temperature range of -40°C to 85°C and is housed in a 9-DSBGA surface-mount package.

Supervisors Feature Summary

• Monitors supply voltage against a fixed 3.08V threshold
• Generates active low reset signal with push-pull output
• Includes minimum 140ms reset timeout for stability

Supervisors Applications

• Microprocessor system supervision
• Power fail input monitoring
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the manufacturer designation, as National Semiconductor assets are managed by Texas Instruments. Confirm the specific suffix '308' matches the required 3.08V threshold. Ensure the package type is 9-DSBGA and check for any RoHS compliance markings on the official datasheet before procurement.

Supervisors Selection Notes

Select this component when a fixed 3.08V monitoring threshold is required for microprocessor systems. The active low reset output suits logic families requiring low-level assertion. Verify that the 140ms minimum timeout meets the system's power-up timing requirements and that the operating temperature range covers the intended environment.

Supervisors Part Context

This part belongs to the LM3704 series of supervisory circuits designed for monitoring power supplies in digital systems. These devices typically integrate voltage detection and reset generation functions into a compact surface-mount package, simplifying board design for embedded applications requiring reliable power management.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the LM3704 family with different threshold voltages if the 3.08V setting does not match the target rail. Verify that substitute components maintain the same 9-DSBGA footprint and electrical characteristics.
