NCV303LSN22T1G

Supervisors Overview

The NCV303LSN22T1G is a supervisory circuit manufactured by onsemi, designed for monitoring single voltage inputs. It operates within a supply voltage range of 800 mV to 10 V and features a threshold voltage of 2 V with an overvoltage threshold of 2.04 V and an undervoltage threshold of 1.96 V. The device provides an active low, open-drain output and includes a programmable reset delay time. It is qualified to AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• AEC-Q100 qualified for automotive reliability requirements
• Programmable reset delay time for flexible timing control
• Low quiescent current consumption of 500 nA
• High accuracy voltage detection with 2% tolerance

Supervisors Applications

• Portable equipment power management
• Microprocessor system supervision
• Battery backup switching circuits
• Automotive electronic control units

Supervisors Procurement Notes

Verify the specific suffix T1G confirms the reel packaging configuration required for your assembly line. Confirm that the NCV prefix designation meets your project's automotive qualification standards compared to commercial variants. Ensure the TSOP-5 package dimensions align with your PCB footprint design rules before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a low-voltage supervisor with adjustable timing is required for space-constrained designs. The 500 nA operating current makes it suitable for battery-powered systems where energy efficiency is critical. The wide operating voltage range allows compatibility with various logic families and power rails without additional level shifting components.

Supervisors Part Context

This part belongs to the NCV303 series of simple reset/voltage detector ICs from onsemi. The series offers multiple threshold options in a compact TSOP-5 package. The NCV prefix indicates automotive-grade qualification, distinguishing it from the commercial NCP303 series which shares similar electrical characteristics but lacks formal automotive certification.
