S-19108N49H-M5T1U

Supervisors Overview

The S-19108N49H-M5T1U is a supervisory circuit manufactured by ABLIC Inc., belonging to the S-19102/19108 series. It functions as a voltage detector with a single monitored input and an open-drain output configuration. The device operates within a maximum supply voltage of 10 V and features a threshold voltage of 4.9 V. It supports surface-mount installation in an SOT-23-5 package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 4.9 V detection threshold
• Features an open-drain output interface for flexible logic integration
• Designed for surface-mount assembly in compact SOT-23-5 packages

Supervisors Applications

• Battery-powered system power supervision
• Microcontroller reset signal generation
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix M5T1U against official ABLIC documentation to confirm packaging and tape-and-reel specifications. Ensure the operating temperature range aligns with your application requirements, as industrial variants may differ. Cross-reference the part number with authorized distributors to confirm current availability and lead times before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.9 V threshold is required for single-input voltage monitoring. The open-drain output necessitates an external pull-up resistor for proper logic level translation. Consider the SOT-23-5 footprint constraints and ensure the PCB layout accommodates the specified thermal and electrical characteristics for reliable long-term operation.

Supervisors Part Context

This part belongs to the S-19102/19108 series of supervisory circuits from ABLIC. These devices are designed for low-power applications requiring accurate voltage detection. The series offers various threshold options and output types to suit different system architectures, providing a standardized solution for power management in consumer and industrial electronics.

Supervisors Replacement Considerations

Check for direct substitutes within the S-19102/19108 series that match the 4.9 V threshold and open-drain output. Verify pin compatibility and package dimensions before substitution to ensure seamless integration without redesigning the printed circuit board.
