NCV301LSN22T1G

Supervisors Overview

The NCV301LSN22T1G is a single-channel voltage detector manufactured by onsemi, designed for monitoring power supply integrity in electronic systems. It operates within a supply voltage range of 800 mV to 10 V and features a precise under-voltage threshold of 2.2 V, with specific limits of 2.156 V minimum and 2.244 V maximum. The device offers 2% accuracy and consumes only 500 nA of operating current. Packaged in a compact 5-TSOP surface-mount format, it supports an extended industrial temperature range from -40°C to +125°C and holds AEC-Q100 qualification for automotive reliability.

Supervisors Feature Summary

• Provides analog under-voltage detection with open-drain output functionality
• Certified for automotive applications through AEC-Q100 qualification
• Engineered for ultra-low power consumption suitable for battery-operated devices

Supervisors Applications

• Automotive electronic control unit (ECU) power supervision
• Portable consumer electronics requiring low standby current
• Industrial equipment power management systems

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm package integrity upon receipt as the TSOP-5 housing is sensitive to moisture. Ensure design compatibility with existing circuit layouts before procurement, as this specific part number is no longer in active production by the manufacturer.

Supervisors Selection Notes

Select this component when a fixed 2.2 V threshold is required for system reset or monitoring. Consider the 500 nA quiescent current for energy-sensitive designs. Verify that the open-drain output configuration aligns with the downstream logic requirements. Evaluate alternative NCV301 variants if different voltage thresholds are needed for the application.

Supervisors Part Context

This device belongs to the NCV301 series of supervisory circuits from onsemi. The series focuses on providing reliable voltage monitoring solutions for automotive and industrial markets. The NCV301LSN22T1G specifically addresses the need for precise under-voltage detection in space-constrained surface-mount applications.

Supervisors Replacement Considerations

NCV301LSN20T1G: Similar supervisor with 2.0 V threshold. NCV301LSN28T1G: Similar supervisor with 2.8 V threshold. NCP301LSN22T1G: Previous generation equivalent with identical electrical characteristics.
