S-19108C48H-M5T1U

Supervisors Overview

The S-19108C48H-M5T1U is a CMOS-based supervisory circuit manufactured by ABLIC Inc., designed for voltage monitoring applications. It operates within an input voltage range of 0.7V to 6.0V and features a fixed detection threshold of 4.8V. The device provides a push-pull/totem pole output with active-low reset functionality and includes a standard reset timeout delay of 40µs. Packaged in an ultra-small SOT-23-5 (SC-74A) surface-mount case, it supports operation across a wide temperature range from -40°C to +105°C. The component holds AEC-Q100 automotive qualification.

Supervisors Feature Summary

• Ultra-compact SOT-23-5 package design for space-constrained PCB layouts
• Automotive-grade reliability certified under AEC-Q100 standards
• Fast response time with 40µs standard reset timeout delay
• Push-pull output structure enabling direct drive capability

Supervisors Applications

• Automotive electronic control unit power supply monitoring
• Battery-operated devices requiring undervoltage protection
• Industrial equipment system supervision
• Portable electronics power management

Supervisors Procurement Notes

Verify the specific suffix 'M5T1U' corresponds to the SOT-23-5 reel packaging configuration. Confirm that the 4.8V threshold aligns with the target system's voltage requirements. Ensure compatibility with the required operating temperature range up to 105°C. Check for any specific ordering codes or alternative suffixes if different packaging quantities are needed. Validate AEC-Q100 certification status for automotive compliance.

Supervisors Selection Notes

Select this component when a low-cost, small-footprint supervisor is required for automotive or industrial environments. The push-pull output is suitable for driving logic inputs directly without external pull-up resistors. Consider the 4.8V threshold carefully to ensure it matches the monitored rail's nominal voltage and dropout characteristics. The wide operating temperature range makes it suitable for harsh environments where standard commercial parts may fail.

Supervisors Part Context

This part belongs to the S-19108 series of voltage detectors from ABLIC. The series utilizes CMOS technology to achieve high accuracy and low current consumption. The S-19108 variant specifically offers a fixed threshold voltage, distinguishing it from adjustable models. It is part of a broader family of supervisory circuits designed for reliable system monitoring in compact packages.

Supervisors Replacement Considerations

Direct substitutes include other S-19108 series variants with different threshold voltages, such as S-19108C33H-M5T1U (3.3V) or S-19108C40H-M5T1U (4.0V), provided the detection level matches the application needs. Cross-reference with similar ABLIC S-19102 or S-19105 series parts if pinout and package compatibility are maintained.
