Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm the exact threshold voltage and output polarity. Ensure the component meets AEC-Q100 requirements if deployed in automotive environments. Confirm package integrity and RoHS compliance status prior to integration. Cross-reference the manufacturer datasheet for precise electrical characteristics and thermal limits.

Supervisors Selection Notes

Select this component when a fixed 1.6 V threshold is required for low-voltage monitoring. Consider the active-low push-pull output for direct logic interfacing. Evaluate the 619 ms reset delay against system startup timing requirements. Verify that the 10 V maximum input rating aligns with the target supply rail.

Supervisors Part Context

This part belongs to the TPS3840 series of voltage supervisors. The PL suffix indicates a specific threshold voltage variant within the family. The DBVR designation identifies the SOT-23-5 surface-mount package type. This series is designed for compact designs requiring precise voltage monitoring.

Supervisors Replacement Considerations

Consult the official TPS3840 family datasheet for compatible alternatives with different thresholds or output types. Verify pinout compatibility before substituting with other variants in the same series.
