LM8364BALMFX27/NOPB

Supervisors Overview

The LM8364BALMFX27/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring single-input power rails. It operates within a supply voltage range of 1 V to 6 V and features an active-low, open-drain output. The device monitors input voltage against a threshold of 2.7 V with an accuracy of 2.5%. It includes a programmable reset delay timer and supports battery backup switching. The component is housed in a SOT-23-5 package and functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides active-low open-drain supervision for single voltage inputs
• Includes programmable reset delay timer functionality
• Supports battery backup switching for continuous monitoring

Supervisors Applications

• Portable electronic devices requiring low quiescent current
• Battery-powered systems needing voltage supervision
• Embedded circuits with limited power budgets

Supervisors Procurement Notes

Verify the specific suffix '27' corresponds to the 2.7 V threshold variant when ordering. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance. Ensure the SOT-23-5 package footprint matches the design layout. Cross-reference the manufacturer part number with official datasheets to confirm electrical specifications before integration.

Supervisors Selection Notes

Select this component when a fixed 2.7 V threshold is required for system supervision. Consider the 2.5% accuracy specification for precision requirements. Evaluate the low quiescent current benefit for battery life extension. Compare against other thresholds in the LM8364 family if different trip points are needed. Verify the active-low output logic compatibility with the target microcontroller or processor reset pin.

Supervisors Part Context

This part belongs to the LM8364 series of micro-power voltage supervisors. It shares the same package and general architecture as variants with different threshold voltages, such as the LM8364BALMFX20/NOPB (2.0 V) and LM8365BALMFX27/NOPB. The series is characterized by low standby current and small footprint, suitable for space-constrained portable applications.

Supervisors Replacement Considerations

Direct substitutes include other LM8364 variants with identical packages but different threshold voltages, such as LM8364BALMFX20/NOPB, if the 2.0 V threshold is acceptable. Generic replacements require matching the SOT-23-5 package, active-low open-drain output, and similar supply voltage ranges.
