NCP301LSN26T1

Supervisors Overview

The NCP301LSN26T1 is a second-generation ultra-low current voltage detector manufactured by onsemi. It features a fixed 2.6V detection threshold and provides an active low/open drain reset output. The component is housed in a 5-pin TSOP package with tape-and-reel packaging. Designed for portable microprocessor systems, it serves as a reset controller to extend battery life.

Supervisors Feature Summary

• Ultra-low current consumption architecture designed to maximize battery longevity in portable applications
• Fixed 2.6V threshold voltage for precise under-voltage monitoring
• Active low or open-drain reset output configuration for flexible logic interfacing

Supervisors Applications

• Microprocessor reset circuits with additional hysteresis
• MCU system load sensing
• Dual power supply under-voltage supervision

Supervisors Procurement Notes

Verify the specific suffix 'T1' against official documentation, as standard listings often utilize 'T1G'. Confirm availability status, as this model may be subject to obsolescence notices from the manufacturer. Ensure the required package type matches the design constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 2.6V threshold is required for supervisory circuits. It is suitable for designs prioritizing minimal quiescent current to preserve battery life in portable devices. Verify that the active low/open drain output aligns with the target microprocessor's reset input requirements.

Supervisors Part Context

This device belongs to the NCP301 series of second-generation ultra-low current voltage detectors. The series includes variants with different fixed thresholds (e.g., 2.5V, 2.7V) tailored for various portable microprocessor-based systems where extended battery operation is critical.

Supervisors Replacement Considerations

Consider the NCP301LSN25T1G for a 2.5V threshold or the NCP301LSN27T1G for a 2.7V threshold if voltage levels differ. Verify pinout compatibility within the 5-pin TSOP package family before substitution.
