BD5230NVX-2CTL

Overview

The BD5230NVX-2CTL is a Nano Energy CMOS reset IC featuring an adjustable delay timer controlled by an external capacitor. It provides under-voltage detection with a typical threshold of 3V and precision of ±2.5%. The device utilizes an N-channel open-drain output, operates within a supply voltage range of 0.8V to 6V, and consumes ultra-low current (0.23µA active, 0.27µA standby). It supports automotive functional safety analysis and maintains delay accuracy within ±50% across the -40°C to 125°C temperature range.
