S-80144ALMC-JA5T2U

Supervisors Overview

The S-80144ALMC-JA5T2U is a high-precision voltage detector from the S-801 series, manufactured by ABLIC Inc. It operates within a supply voltage range of 0.7 V to 6.0 V and features a fixed threshold voltage of 4.4 V with an accuracy of ±1%. The device utilizes a CMOS process and includes an internal delay circuit generator set to a typical reset timeout of 32.5 ms. It provides a push-pull output in a compact SOT-23-5 package, suitable for monitoring single voltage rails.

Supervisors Feature Summary

• High-precision voltage detection with built-in delay time generator
• Push-pull output configuration for direct logic interfacing
• Compact SOT-23-5 package design

Supervisors Applications

• Portable electronic devices requiring precise power monitoring
• Battery-powered systems needing reliable voltage supervision
• Embedded circuits with strict reset timing requirements

Supervisors Procurement Notes

Verify the specific suffix JA5T2U against official ABLIC documentation to confirm the exact threshold voltage and delay characteristics. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Cross-reference RoHS compliance status with current manufacturer declarations before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold and approximately 32.5 ms delay are required. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Consider the SOT-23-5 form factor for space-constrained designs where standard supervisor ICs may be too large.

Supervisors Part Context

This part belongs to the S-801 series of voltage detectors developed using CMOS technology. The series is characterized by high precision and low power consumption. The S-80144 variant specifically targets applications requiring a 4.4 V monitoring level, distinguishing it from other thresholds available in the broader S-801 family lineup.

Supervisors Replacement Considerations

Direct substitutes include other S-801 series parts with similar threshold voltages, such as the S-80143 or S-80145, provided the delay characteristics align with system requirements. Verify pinout compatibility for the SOT-23-5 package before substitution.
