LM8364BALMFX20/NOPB

Supervisors Overview

The LM8364BALMFX20/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed for active-low voltage monitoring applications. It operates within a supply voltage range of 1 V to 6 V and features a fixed threshold voltage of 2 V with an accuracy of 2.5%. The device utilizes an SOT-23-5 package and provides an open-drain output. Key specifications include an under-voltage threshold of 1.95 V and an over-voltage threshold of 2.05 V. It supports power-fail detection and battery backup switching without manual reset or watchdog timer functionality.

Supervisors Feature Summary

• Active-low voltage monitoring with open-drain output capability
• Integrated power-fail detection and battery backup switching
• Fixed threshold voltage design ensuring precise supervision

Supervisors Applications

• Monitoring critical voltage rails in embedded systems
• Battery-powered device supervision and backup switching
• Power-fail signal generation for microcontroller reset circuits

Supervisors Procurement Notes

Verify the specific suffix 'F20' against official datasheets to confirm the 2 V threshold variant. Ensure the ordering part number matches the required tolerance and package type. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and any recent product change notifications affecting this specific revision.

Supervisors Selection Notes

Select this component when a fixed 2 V threshold is required for low-voltage monitoring. Consider the SOT-23-5 package size constraints and the open-drain output requirement for pull-up configuration. Evaluate the 2.5% accuracy specification against system tolerance needs. Confirm that the absence of a manual reset and watchdog timer aligns with the application's control logic requirements.

Supervisors Part Context

This part belongs to the LM8364 series of voltage supervisors from Texas Instruments. It is categorized under PMIC - Power Management ICs and specifically Supervisory Circuits. The device shares the SOT-23-5 package form factor common to other low-power monitoring solutions in the portfolio, focusing on single-input voltage supervision without additional complexity like programmable delays or watchdog timers.

Supervisors Replacement Considerations

LM8365BALMFX20/NOPB offers similar functionality but includes programmable reset delay times instead of a fixed threshold response profile.
