S-19405G50A-K8T2U4

Supervisors Overview

The S-19405G50A-K8T2U4 is a voltage monitor and watchdog timer manufactured by ABLIC Inc. It operates within a supply voltage range of up to 6 V and features a threshold voltage of 5.0 V. The device provides an active high CMOS output and includes manual reset functionality with a reset delay time of 25 µs. It is housed in a TMSOP-8 package suitable for surface mount installation. The component supports a wide operating temperature range from -40 °C to +125 °C, ensuring reliability in demanding environments.

Supervisors Feature Summary

• Integrates voltage monitoring and watchdog timer functions in a single chip
• Provides active high CMOS output signal for system supervision
• Supports manual reset input for controlled system recovery

Supervisors Applications

• Embedded systems requiring voltage supervision
• Industrial control units needing watchdog protection
• Automotive electronics operating in harsh thermal conditions

Supervisors Procurement Notes

Verify the specific suffix K8T2U4 against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the 5.0 V threshold voltage aligns with your system's power rail requirements. Confirm RoHS compliance status directly with ABLIC or authorized distributors before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a combined voltage monitor and watchdog timer is required for space-constrained designs. The TMSOP-8 package offers a compact footprint compared to larger alternatives. Consider the 25 µs reset delay and active high output polarity during circuit design to ensure compatibility with downstream logic gates and microcontroller reset pins.

Supervisors Part Context

This part belongs to the S-19405 series of supervisory circuits from ABLIC. The series is designed for applications requiring reliable power management and system stability. The G50A designation indicates the specific 5.0 V threshold voltage variant within this family, distinguishing it from other threshold options available in the same product line.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the S-19405 series that match the 5.0 V threshold. Verify that alternative parts maintain the same active high output configuration and watchdog timer functionality to avoid redesigning the surrounding circuitry.
