LM8365BALMF27/NOPB

Supervisors Overview

The LM8365BALMF27/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 specifies a threshold voltage of 2.7 V with an accuracy of 2.5%. It includes a programmable reset delay timer and supports battery backup switching functionality. The component is housed in a SOT-23-5 package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Provides active-low open-drain reset signaling for monitored power supplies
• Features programmable reset delay timing for customized system response
• Supports battery backup switching to maintain supervision during power transitions

Supervisors Applications

• Monitoring microprocessor and microcontroller power rails
• Supervising memory subsystem voltage integrity
• Ensuring reliable startup sequences in embedded systems

Supervisors Procurement Notes

Verify the specific suffix configuration against the manufacturer's official documentation to ensure compatibility with required threshold voltages and packaging options. Confirm that the SOT-23-5 footprint matches the target PCB design constraints. Cross-reference the operating temperature range with the intended application environment to guarantee performance stability under all expected conditions.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with low quiescent current is required. The 2.7 V threshold suits applications where the supply rail operates at or above this level. Consider the programmable delay feature if system-specific startup timing is necessary. Ensure the open-drain output capability aligns with the downstream logic interface requirements.

Supervisors Part Context

This part belongs to the LM8365 series of MicroPwr under-voltage sensing circuits from Texas Instruments. It is categorized under PMIC supervisory circuits. The device shares architectural similarities with other members of the family but differs in threshold specifications and suffix codes. It serves as a dedicated solution for power management reliability in compact electronic designs.

Supervisors Replacement Considerations

Direct substitutes include other LM8365 variants with matching thresholds or compatible pinouts. Verify electrical parameters such as threshold accuracy and reset delay ranges before substitution. Ensure the replacement maintains the same package type and operating temperature specifications.
