NCP303LSN09T1G Description

Short technical summary and product information.

The NCP303LSN09T1G from ON Semiconductor is a second-generation, ultra-low current voltage detector with a programmable time delay generator. It is designed for use as reset controllers in portable microprocessor-based systems where extended battery life is critical.

 

This device features a highly accurate undervoltage detector with hysteresis and an externally programmable time delay generator, preventing erratic system reset operations. The NCP303 series, including the NCP303LSN09T1G, has an open-drain N-channel output with an active-low reset.

 

Key electrical specifications include a quiescent current of 0.5 µA typical, a high accuracy undervoltage threshold of 2.0%, and a wide operating voltage range from 0.8 V to 10 V. The operating temperature range is -40°C to +125°C, with specific voltage options operating from -40°C to +85°C.

 

The NCP303LSN09T1G is available in a 5-TSOP package and is surface-mountable. Typical applications include microprocessor reset controllers, low battery detection, power fail indicators, and battery backup detection.
