NCP302LSN45T1G Description

Short technical summary and product information.

The NCP302LSN45T1G is a voltage supervisor IC manufactured by ON Semiconductor. It monitors a single voltage channel with a fixed threshold of 4.5V and offers high accuracy of 2.0%.

 

The device operates over a wide supply voltage range from 0.8V to 10V, making it suitable for various low-power and battery-powered applications. Typical quiescent current is only 0.5µA, minimizing power consumption in standby and active modes.

 

Designed for robust performance, the NCP302LSN45T1G operates over an industrial temperature range of -40°C to 125°C. It is housed in a 5-lead TSOP (5TSOP) surface-mount package, suitable for compact PCB layouts.

 

Applications include portable electronics, microcontroller systems, automotive electronics, and industrial control systems where reliable voltage monitoring and low power are critical.
