Description

The NCP304LSQ09T1 is a voltage detector series, specifically designed for use as reset controllers in portable microprocessor-based systems where extended battery life is paramount. It features a highly accurate undervoltage detector with hysteresis to prevent erratic system reset operation. The NCP304LSQ09T1 consists of complementary output devices that are available with either an active high or active low reset output. It operates in a wide voltage range of 0.8 V to 10 V and has a quiescent current of 1.0 μA typical. This model is commonly used as a microprocessor reset controller, for low battery detection, power fail indicator, and battery backup detection.
