S-19105N33H-M5T1U

Supervisors Overview

The S-19105N33H-M5T1U is a supervisory circuit manufactured by ABLIC Inc., belonging to the S-19105/19107 series. It functions as a voltage detector with a threshold voltage of 3.3V and an active low open drain output. The device operates within a supply voltage range up to 6.0V and features a standard reset delay time of 40µs. It is qualified to AEC-Q100 automotive standards and supports an operating temperature range from -40°C to +105°C. The component is housed in an SOT-23-5 package.

Supervisors Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for reliable operation in vehicle environments.
• Open-drain output configuration provides flexibility for interfacing with various logic families.
• Compact surface-mount packaging facilitates integration into space-constrained electronic designs.

Supervisors Applications

• Monitoring power supply voltages in automotive electronic control units.
• Providing reset signals for microcontrollers in industrial systems.
• Detecting under-voltage conditions in battery-powered devices.

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct threshold voltage and output type. Confirm AEC-Q100 compliance requirements match your application's environmental standards. Check lead times as automotive components may have extended production cycles. Ensure compatibility with your system's logic levels given the open-drain output structure.

Supervisors Selection Notes

Select this component when a 3.3V detection threshold is required for automotive or industrial applications. The open-drain output necessitates an external pull-up resistor, which should be chosen based on system speed and voltage requirements. Consider the 40µs reset delay when designing timing-critical circuits. Verify that the SOT-23-5 package fits your PCB layout constraints.

Supervisors Part Context

This part belongs to the S-19105 series of voltage detectors from ABLIC. The series offers various threshold voltages and output configurations to suit different monitoring needs. The S-19105N33H variant specifically targets applications requiring precise 3.3V level detection with automotive reliability.

Supervisors Replacement Considerations

Direct substitutes include other parts from the S-19105 series with identical 3.3V thresholds and open-drain outputs. Verify pinout compatibility and electrical specifications before substitution. Alternative manufacturers may offer similar features but require validation of automotive qualification status.
