LM8364BALMF20/NOPB

Supervisors Overview

The LM8364BALMF20/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 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 across an operating temperature range of -40°C to +85°C.

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 power rails in embedded systems
• Supervising voltage levels in portable electronic devices
• Ensuring system stability in industrial control applications

Supervisors Procurement Notes

Verify the exact part number suffix against official Texas Instruments documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint, specifically the SOT-23-5 package dimensions. Confirm that the required voltage thresholds align with the specific application's under-voltage and over-voltage requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with low quiescent current is required. It 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 1 V to 6 V input range covers the monitored rail.

Supervisors Part Context

This component belongs to the LM8364 series of micro-power voltage supervisors from Texas Instruments. These devices are engineered for low-power applications requiring reliable power management. The series typically offers various threshold options and packaging configurations to suit different design constraints while maintaining high accuracy and low standby current consumption.

Supervisors Replacement Considerations

Consult official substitution guides for compatible parts within the LM836x family or equivalent Texas Instruments voltage supervisors. Verify that any alternative maintains the same SOT-23-5 footprint and electrical specifications.
