S-1004LB38I-M5T1U

Supervisors Overview

The S-1004LB38I-M5T1U is a single-channel voltage detector manufactured by ABLIC Inc., designed for monitoring power supply integrity in electronic systems. It operates within a supply voltage range of up to 6.0 V and features a detection threshold of 3.8 V. The device utilizes an open-drain output configuration with active-low reset signaling. It is housed in a compact SC-74A (SOT-753) surface-mount package, suitable for space-constrained designs. The component supports an operating temperature range from -40°C to +85°C, ensuring reliability across industrial and commercial environments.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 3.8 V detection threshold
• Features low quiescent current consumption for battery-powered applications
• Delivers active-low reset signal via open-drain output interface
• Utilizes small footprint SC-74A package for efficient board layout

Supervisors Applications

• Microcontroller system power monitoring
• Battery-operated device voltage supervision

Supervisors Procurement Notes

Verify the complete part number including suffixes against official ABLIC documentation to ensure correct threshold voltage and package type. Confirm RoHS compliance status and specific manufacturing date codes during sourcing. Cross-reference distributor listings with manufacturer datasheets to validate authenticity and avoid counterfeit components. Check for any recent lifecycle notices or obsolescence warnings before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 3.8 V threshold is required for system reset logic. Ensure the open-drain output compatibility matches the downstream microcontroller input requirements. Verify that the maximum supply voltage rating aligns with the highest expected system voltage. Consider the thermal performance and package size constraints relative to the target application environment.

Supervisors Part Context

This device belongs to the S-1004 series of voltage detectors from ABLIC Inc., which offers various threshold options within the same package family. The series is characterized by low power consumption and high accuracy, making it suitable for modern portable and industrial electronics. The S-1004LB38I variant specifically targets applications requiring a 3.8 V supervision level.

Supervisors Replacement Considerations

Direct substitutes include other S-1004 series variants with identical packages but different thresholds, such as S-1004LB33I or S-1004LB40I, if threshold adjustments are permissible. Generic equivalents from other manufacturers may require verification of pinout compatibility and electrical parameter alignment.
