LM8364BALMFX20

Supervisors Overview

The LM8364BALMFX20/NOPB is an active-low voltage monitor from Texas Instruments designed for low quiescent current applications. It features a single monitored input with an open-drain output. The device operates within a supply voltage range of 1 V to 6 V and includes a battery backup switch. It provides power failure detection with specific thresholds: under-voltage at 1.95 V, over-voltage at 2.05 V, and a general threshold of 2 V. Accuracy is specified at 2.5%. The component is housed in a SOT-23-5 package and functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Active-low reset IC with low quiescent current consumption
• Integrated battery backup switch functionality
• Power failure detection capability
• Open-drain output configuration

Supervisors Applications

• Voltage supervision in portable electronics
• Battery-powered system monitoring
• Power management circuits requiring low standby current

Supervisors Procurement Notes

Verify the complete part number including the NOPB suffix to ensure compliance with lead-free standards and RoHS directives. Confirm that the SOT-23-5 package variant matches your PCB footprint requirements. Ensure the operating temperature range aligns with your environmental specifications. Cross-reference the datasheet for electrical characteristics relevant to your specific application voltage levels.

Supervisors Selection Notes

Choose this component when a single-channel voltage monitor with minimal current draw is required. The fixed threshold values suit applications where precise voltage tracking is necessary without external resistor networks. Consider the open-drain output compatibility with your logic levels. The absence of a manual reset or watchdog timer simplifies design but limits complexity compared to multi-function supervisors.

Supervisors Part Context

This part belongs to the LM8364 series of supervisory circuits. It is categorized under PMIC - Power Management ICs. The device serves as a dedicated voltage monitor rather than a general-purpose regulator. Its primary role is to detect out-of-specification voltage conditions and signal the system accordingly.
