LM8365BALMFX22

Supervisors Overview

The LM8365BALMFX22/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 provides a programmable reset delay time and includes a battery backup switch function. It is housed in a SOT-23-5 surface-mount package and maintains an accuracy of 2.5%. The component supports operation across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides active-low reset signaling with open-drain output configuration
• Includes battery backup switch functionality for continuous monitoring during power transitions
• Features programmable reset delay timing for customized system response

Supervisors Applications

• Portable electronic devices requiring low quiescent current monitoring
• Battery-powered systems needing backup switch supervision
• Embedded circuits utilizing single-rail voltage supervision

Supervisors Procurement Notes

Verify the specific threshold voltage suffix (e.g., 22 for 2.2V) against design requirements. Confirm RoHS compliance status via official datasheets. Ensure ESD handling protocols are followed due to the small SOT-23-5 package. Cross-reference ordering part numbers with manufacturer documentation to avoid variant mismatches.

Supervisors Selection Notes

Select this component when a low-voltage supervisor with battery backup support is required. The SOT-23-5 package suits space-constrained designs. Verify that the 2.5% accuracy meets system tolerance needs. Consider the programmable delay feature if specific startup sequencing is necessary for the target application.

Supervisors Part Context

This part belongs to the LM8365 series of MicroPwr under-voltage sensing circuits. It complements other variants like the LM8365BALMFX27/NOPB and LM8365BALMFX45/NOPB, which share similar architectures but differ in threshold voltages. The series focuses on low-power applications requiring reliable voltage supervision.

Supervisors Replacement Considerations

Direct substitutes include other LM8365 variants with matching threshold voltages. Verify pin compatibility and package dimensions before substitution. Ensure functional equivalence regarding battery backup and reset delay capabilities.
