NCV303LSN34T1G Description

Short technical summary and product information.

The NCV303LSN34T1G from ON Semiconductor is a second-generation, ultra-low current voltage detector designed for microprocessor reset control in portable systems. It features a highly accurate undervoltage detector with hysteresis and an externally programmable time delay generator to prevent erratic system resets.

 

Key electrical specifications include a nominal voltage of 3.4V, an operating voltage range from 0.8V to 10V, and a low quiescent current of 0.5µA typical. The device offers an adjustable or selectable reset timeout and an active low reset output. The output configuration is open drain or open collector, suitable for monitoring a single voltage.

 

This voltage detector operates within a temperature range of -40°C to +125°C. It is supplied in a SOT-23-5 Thin package, requiring surface mount technology. The NCV303LSN34T1G is Pb-free and RoHS compliant, making it suitable for various electronic designs where reliable power monitoring is critical.
