S-19103C19H-M5T1U

Supervisors Overview

The S-19103C19H-M5T1U is a supervisory circuit manufactured by ABLIC Inc., belonging to the S-19103/19109 series. It functions as a voltage detector with a fixed threshold voltage of 1.9 V. The device features an active low, CMOS output type and includes a reset delay time of 26 ms. It operates within a supply voltage range up to 10 V and supports a single monitored input. The component is designed for surface mount installation in an SOT-23-5 package and operates across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides undervoltage detection with a fixed threshold voltage.
• Features an active low CMOS output interface.
• Includes a built-in reset delay timer for stable operation.

Supervisors Applications

• Monitoring power supply voltages in electronic systems
• Providing reset signals for microcontrollers and processors
• Ensuring system stability during power-up and power-down sequences

Supervisors Procurement Notes

Verify the specific suffix M5T1U corresponds to the SOT-23-5 reel packaging configuration. Confirm the 1.9 V threshold requirement matches the target application's voltage monitoring needs. Ensure compatibility with the specified operating temperature range and supply voltage limits before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 1.9 V detection threshold is required for system supervision. The active low output is suitable for interfacing with logic circuits expecting a low signal upon fault detection. Consider the 26 ms delay if fast transient immunity is not critical. Verify that the 10 V maximum supply voltage accommodates the highest expected input voltage in the design.

Supervisors Part Context

This part belongs to the ABLIC S-19103/19109 series of supervisory circuits. These devices are designed for high reliability and compact size. The series utilizes CMOS technology to achieve low current consumption. The S-19103 variant specifically offers fixed threshold options for standard voltage monitoring applications.

Supervisors Replacement Considerations

Check for other parts within the S-19103 series with different threshold voltages if 1.9 V is not exact. Compare pinout compatibility with other SOT-23-5 voltage detectors from ABLIC or competitors. Ensure replacement parts support the same active low output polarity and reset delay characteristics.
