The NCP302LSN30T1G is an integrated circuit (IC) component designed and manufactured by ON Semiconductor. It is a voltage supervisor or detector specifically used for monitoring the power supply voltage in electronic devices and systems. The IC ensures reliable system operation by providing reset signals when the power supply voltage falls below a specified threshold.
Some key features of the NCP302LSN30T1G include:
1. Voltage Monitoring: The IC continuously monitors the power supply voltage with a threshold of 3.0V, making it suitable for applications with a minimum supply voltage requirement of up to 3.0V.
2. Accurate Reset Generation: When the supply voltage drops below the specified threshold, the NCP302LSN30T1G generates a reset signal, guaranteeing that the system restarts correctly. The reset signal remains active until the power supply voltage rises above the threshold voltage, ensuring accurate reset generation.
3. Adjustable Delay Time: The IC incorporates a fixed delay time of 140ms (typical). However, an external capacitor connected to the CT pin allows customizing the reset delay time as per the application's requirements.
4. Built-In Hysteresis: The NCP302LSN30T1G includes built-in hysteresis on the power supply voltage threshold to prevent the generation of spurious reset signals due to noise or voltage fluctuations. It ensures a robust and reliable reset function
