S-19104C43H-M5T1U

Supervisors Overview

The S-19104C43H-M5T1U is a voltage detector manufactured by ABLIC Inc., designed for supervisory circuit applications. It operates within an input voltage range of 0.95V to 10V and features a fixed threshold voltage of 4.3V. The device utilizes a push-pull or totem pole output configuration and includes a built-in delay circuit with a standard reset timeout of 40µs. Packaged in a 5-pin SOT-23 (SC-74A) format, it supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a built-in delay circuit to prevent false triggering during power supply transitions.
• Provides a push-pull output stage capable of driving subsequent logic circuits directly.
• Offers high accuracy monitoring with a fixed threshold voltage specification.

Supervisors Applications

• Microprocessor system reset generation
• Battery-powered device power management
• Portable equipment voltage supervision

Supervisors Procurement Notes

Verify the specific suffix M5T1U corresponds to the reel packaging quantity of 3000 units when placing orders. Confirm that the 4.3V threshold aligns with the target system's voltage requirements. Ensure compatibility with the SOT-23-5 footprint during PCB layout. Check for RoHS compliance status if required by local regulations.

Supervisors Selection Notes

Select this component when a precise 4.3V detection level is required for systems operating between 0.95V and 10V. The push-pull output is suitable for applications needing active drive capability rather than open-drain configurations. Consider the 40µs delay for noise immunity against transient voltage spikes on the power rail.

Supervisors Part Context

This part belongs to the S-19104/19106 series of voltage detectors from ABLIC. These devices are engineered for low-power consumption and high reliability in portable electronics. The series typically offers various threshold options to accommodate different logic families and power rails.

Supervisors Replacement Considerations

S-19104C26H-M5T1U is listed as a parameter equivalent alternative within the same series, though it features a different threshold voltage of 2.6V. Verify electrical compatibility before substitution.
