S-80137BLPF-JEWTFU

Supervisors Overview

The S-80137BLPF-JEWTFU is a supervisory circuit manufactured by ABLIC Inc. It operates within a supply voltage range of 950 mV to 10 V and features a fixed voltage threshold of 3.7 V. The device utilizes an SNT-4A package with four flat leads. It provides a minimum reset timeout of 65 ms and employs a push-pull, totem pole output configuration. Designed for single-channel monitoring, it supports surface-mount installation and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a high-precision voltage detection mechanism with a fixed 3.7 V threshold for reliable system supervision.
• Features a push-pull, totem pole output stage capable of driving downstream logic or control circuits directly.
• Includes a built-in delay circuit ensuring a minimum reset timeout of 65 ms to prevent false triggering during power transitions.

Supervisors Applications

• Monitoring battery pack voltage levels in portable electronic devices
• Supervising microcontroller power rails in embedded systems
• Providing reset signals for digital logic circuits in industrial control equipment

Supervisors Procurement Notes

Verify the specific suffix JEWTFU against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the SNT-4A package dimensions align with the target PCB footprint. Confirm that the 3.7 V threshold meets the system's undervoltage lockout requirements before finalizing the design.

Supervisors Selection Notes

Select this component when a fixed 3.7 V threshold is required for system supervision. The SNT-4A package offers a compact solution for space-constrained designs. Consider the push-pull output capability if direct drive of subsequent stages is necessary without additional buffering components.

Supervisors Part Context

This part belongs to the S-801 series of voltage detectors from ABLIC Inc. The series focuses on ultra-small packages and high-precision monitoring solutions. The S-80137 variant specifically targets applications requiring a 3.7 V detection point, commonly associated with lithium-ion battery management.

Supervisors Replacement Considerations

Cross-reference with other S-801 series parts like S-80136ALPF-JAVTFG for different thresholds. Verify functional equivalence with generic supervisor ICs offering similar 3.7 V thresholds and SNT-4A packaging.
