NCV303LSN29T1G

Supervisors Overview

The NCV303LSN29T1G is a single-channel voltage detector from the NCV303 series, designed for supervisory applications in automotive and industrial environments. It operates within a supply voltage range of 800 mV to 10 V and features a threshold voltage of 2.9 V with 2% accuracy. The device provides an active low, open-drain output and includes a programmable reset delay time. It supports battery backup switching and is qualified under AEC-Q100 standards. Operating temperatures span from -40°C to +125°C, ensuring reliability across harsh conditions.

Supervisors Feature Summary

• Features a programmable reset delay time for customized timing control.
• Includes battery backup switching capability to maintain system integrity during power transitions.
• Delivers an active low, open-drain output signal for direct interface with digital logic.

Supervisors Applications

• Automotive electronic systems requiring AEC-Q100 qualified supervision
• Industrial equipment monitoring critical voltage levels
• Battery-powered devices utilizing backup switching functions

Supervisors Procurement Notes

Verify the specific package variant and tape-and-reel specifications against the official datasheet before ordering. Confirm that the AEC-Q100 qualification aligns with your project's automotive compliance requirements. Ensure the TSOP-5 footprint matches your PCB layout constraints. Cross-reference the manufacturer part number to avoid confusion with non-automotive grade equivalents.

Supervisors Selection Notes

Select this component when a precise 2.9 V detection threshold is required for single-supply monitoring. The low quiescent current makes it suitable for power-sensitive designs. Consider the programmable reset delay if system startup sequencing demands specific timing margins. Verify compatibility with the target operating temperature range for automotive or industrial deployment.

Supervisors Part Context

This part belongs to the NCV303 family of analog undervoltage detectors manufactured by onsemi. The 'NCV' prefix indicates automotive-grade qualification, distinguishing it from commercial variants like the NCP303 series. These devices are designed to replace older supervisor ICs with improved accuracy and lower power consumption in modern embedded systems.

Supervisors Replacement Considerations

Check for NCV303LSNxxT1G variants with different threshold voltages if the 2.9 V setting is not optimal. Non-automotive NCP303LSN29T1G may serve as a functional substitute if automotive qualification is not mandatory.
