Introduction to NCV303LSN30T1

The NCV303LSN30T1 belongs to the PMIC - Supervisors family. It is a low quiescent current, high accuracy Supervisory device which integrates two functions in one package: dual voltage monitoring and system reset.

Application Field

The NCV303LSN30T1 is suitable for use in a wide range of applications. It is useful in systems with low system power and is designed to monitor supply voltages from 3.0 to 5.5V. It is particularly useful in applications such as embedded systems, motor and motor control systems, power supplies, solar systems and other applications that require under-voltage protection and/or reset.

Features

The NCV303LSN30T1 includes a number of features to ensure high accuracy. These include:* Accurate reset thresholds: The NCV303LSN30T1 provides a reset voltage (Vreset) as low as 3V, ensuring maximum reliability and accuracy.* Adjustable reset thresholds: The NCV303LSN30T1 features an adjustable reset levels which allows the user to set a reset voltage for the system.* Low quiescent current: The NCV303LSN30T1 is designed to consume a very low quiescent current, typically 100 nA. This ensures a longer battery life and improved system reliability.

Working Principle

The NCV303LSN30T1 works by comparing the voltage of a monitored supply against an adjustable reset threshold, Vreset. If the monitored voltage drops below the Vreset deflection, the supervisor will trigger a reset to the system. The NCV303LSN 30T1 also provides an adjustable reset delay which allows the user to control the length of time before the reset is triggered.

Conclusion

The NCV303LSN 30T1 is a low quiescent current, high accuracy PMIC supervisor. It is useful in systems with low system power, and is designed to monitor supply voltages from 3.0 to 5.5V. It includes a number of features to ensure high accuracy and reliability, such as adjustable reset levels and delays, to ensure a maximum level of protection for the system. Additionally, the low quiescent current ensures a longer battery life and improved system reliability.
