S-19105N48H-M5T1U

Supervisors Overview

The S-19105N48H-M5T1U is a single-channel voltage detector manufactured by ABLIC Inc., designed for supervisory circuit applications. It operates within an input voltage range of 0.8 V to 6.0 V and features a fixed detection threshold of 4.8 V. The device utilizes an open-drain output configuration, ensuring compatibility with various logic families. It includes a standard reset delay time of 200 µs to prevent false triggering during power transitions. The component is qualified under the AEC-Q100 automotive grade standard, supporting reliable operation across a wide ambient temperature range from -40°C to +105°C.

Supervisors Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Open-drain output interface for flexible logic integration
• Wide operating temperature range suitable for harsh environments

Supervisors Applications

• Automotive electronic system monitoring
• Microprocessor reset circuits in industrial controllers
• Battery voltage supervision in portable devices

Supervisors Procurement Notes

Verify that the specific suffix M5T1U corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 4.8 V threshold aligns precisely with your system's trip point requirements. Ensure that the open-drain output capability matches your pull-up resistor configuration. Validate that the AEC-Q100 qualification meets your specific automotive or industrial compliance standards before finalizing procurement.

Supervisors Selection Notes

Select this component when a precise 4.8 V detection threshold is required for systems operating up to 6.0 V. The open-drain output is ideal for interfacing with microcontrollers requiring active-low reset signals. Consider the AEC-Q100 qualification if the application demands automotive-grade reliability. The SOT-23-5 package offers a compact footprint suitable for space-constrained designs. Evaluate the 200 µs reset delay against your system's startup timing constraints.

Supervisors Part Context

This part belongs to the S-19105 series of voltage detectors from ABLIC, which are designed for high-reliability applications. The series is characterized by low current consumption and high accuracy. The S-19105N48H variant specifically denotes the 4.8 V threshold version within this family. It shares the same pinout and functional architecture as other thresholds in the series, differing only in the internal reference voltage setting.

Supervisors Replacement Considerations

Direct substitutes include other S-19105 series parts with different voltage thresholds if the trip point can be adjusted. Cross-reference with similar ABLIC voltage detectors like the S-19102 series for comparable performance. Verify that any replacement maintains the open-drain output and AEC-Q100 qualification if automotive use is intended.
