S-1003NA50I-M5T1U

Supervisors Overview

The S-1003NA50I-M5T1U is a voltage detector from the S-1003 series manufactured by ABLIC Inc. It features a fixed detection threshold of 5.0 V with high accuracy. The device operates within a supply voltage range up to 10 V and includes a manual reset function alongside a delay timer. It utilizes an active low, open-drain output configuration. The component is housed in a compact SOT-23-5 package and supports surface-mount installation. It functions as a supervisory circuit for monitoring power rails.

Supervisors Feature Summary

• Incorporates a manual reset capability for controlled system recovery
• Features a built-in delay timer to prevent false triggering during power transitions
• Provides an active low open-drain output signal for interface compatibility

Supervisors Applications

• Monitoring battery voltage levels in portable electronic devices
• Supervising power supplies in embedded control systems
• Ensuring stable operation in microprocessor-based circuits

Supervisors Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the SOT-23-5 footprint aligns with your PCB layout constraints. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a 5.0 V detection threshold is required for power supervision. The manual reset feature distinguishes it from standard detectors lacking user intervention capabilities. Verify that the open-drain output suits your logic level requirements. Consider the operating temperature range and package size relative to your enclosure specifications.

Supervisors Part Context

This part belongs to the S-1003 series of CMOS voltage detectors developed by ABLIC Inc. The series offers fixed internal detection voltages with high precision. These devices are designed for reliable power management applications requiring accurate threshold monitoring and delayed reset responses.

Supervisors Replacement Considerations

Cross-reference with other S-1003 series variants having different detection thresholds if voltage requirements change. Verify functional equivalence regarding manual reset and delay timer presence when substituting with similar supervisor ICs from other manufacturers.
