LM8364BALMF20

Supervisors Overview

The LM8364BALMF20 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 detects under-voltage conditions at a threshold of 1.95 V and over-voltage conditions at 2.05 V, maintaining an accuracy of 2.5%. It includes a battery backup switch function but lacks manual reset or watchdog timer capabilities. The component is housed in a SOT-23-5 package and supports surface-mount installation.

Supervisors Feature Summary

• Provides active-low open-drain output signaling for power failure detection
• Integrates a battery backup switch to maintain monitoring during power transitions
• Delivers precise voltage supervision with specified under-voltage and over-voltage thresholds

Supervisors Applications

• Monitoring critical voltage rails in embedded systems
• Power management circuits requiring low quiescent current operation
• Battery-powered devices needing reliable voltage supervision

Supervisors Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations such as LM8364BALMFX20/NOPB exist within the same family. Confirm that the specific part number matches the required threshold voltage and packaging format. Ensure compatibility with RoHS standards and check for any specific ordering suffixes that may affect availability or specifications.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with low operating voltage is required. The LM8364BALMF20 is suitable for applications needing both under-voltage and over-voltage detection without manual reset functionality. Consider the SOT-23-5 package size for space-constrained designs and verify that the 2.5% accuracy meets system requirements.

Supervisors Part Context

This component belongs to the LM8364 series of voltage supervisory circuits from Texas Instruments. It is categorized under PMIC - Power Management ICs and serves as a dedicated solution for power monitoring tasks. The device is distinct from other series like the LM8365, which offers programmable reset delays, by providing fixed threshold monitoring with a focus on simplicity and low power consumption.
