S-19109N34H-M5T1U

Supervisors Overview

The S-19109N34H-M5T1U is a supervisory circuit manufactured by ABLIC Inc., belonging to the S-19103/19109 series. It functions as a voltage detector housed in an SC-74A, SOT-753 package with five pins. The device monitors a single input channel and features a threshold voltage of 3.4V. It provides an active low output using a push-pull/totem pole configuration. The component operates within a temperature range of -40°C to 105°C and holds AEC-Q100 automotive qualification.

Supervisors Feature Summary

• Automotive-grade voltage detection capability certified under AEC-Q100 standards for reliable operation in demanding environments.
• Ultra-compact surface-mount packaging design facilitates integration into space-constrained electronic circuits.
• Push-pull output architecture ensures robust signal driving without requiring external pull-up resistors.

Supervisors Applications

• Monitoring power supply integrity in automotive electronic control units
• Providing reset signals for microprocessors in vehicle infotainment systems
• Detecting undervoltage conditions in battery-powered automotive modules

Supervisors Procurement Notes

Verify current availability status directly with authorized distributors or the manufacturer, as lead times may vary. Confirm that the specific ordering suffix matches the required package type and temperature grade. Ensure compliance with RoHS directives and check for any regional distribution restrictions before finalizing procurement orders.

Supervisors Selection Notes

Select this component when an automotive-qualified voltage detector with a 3.4V threshold is required. The push-pull output simplifies interface design compared to open-drain alternatives. Consider the SOT-753 footprint for board space optimization. Validate that the operating temperature range meets the specific application environmental requirements.

Supervisors Part Context

This part belongs to the S-19109 series of supervisory circuits from ABLIC Inc. The series is characterized by high accuracy and low current consumption built using CMOS technology. These devices are designed specifically for applications requiring reliable voltage monitoring in automotive and industrial sectors where stability and precision are critical.

Supervisors Replacement Considerations

S-19109C26H-M5T1U is listed as a parameter-equivalent alternative within the same series. Verify that the threshold voltage difference does not impact system logic levels. Other variants in the S-19103/19109 family may offer different thresholds but share similar package and electrical characteristics.
