NCP304LSQ32T1

Supervisors Overview

The NCP304LSQ32T1 is a voltage detector from onsemi designed for power supply supervision. It features a fixed threshold of 3.2V with an overvoltage limit of 3.264V and an undervoltage limit of 3.136V. The device operates within a supply voltage range of 800mV to 10V and maintains a typical accuracy of 2%. It draws a low quiescent current of 1µA and provides an active-low, open-drain reset output. The component supports battery backup switching and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 3.2V detection threshold
• Features ultra-low quiescent current consumption for energy efficiency
• Includes battery backup functionality to maintain system state during power transitions

Supervisors Applications

• Portable electronic devices requiring extended battery life
