BD521VNVX-2CTL

Overview

The BD521VNVX-2CTL is a Nano Energy™ automotive-grade CMOS voltage detector IC with a typical detection voltage of 0.965V. It features an adjustable reset delay timer controlled by an external capacitor, maintaining ±50% accuracy from -40°C to 125°C. The device utilizes an Nch open-drain output and operates within a reset active voltage range of 0.8V to 6V. Key electrical parameters include a circuit current of 0.23µA (ON) and 0.27µA (OFF), hysteresis of VDET x 0.05, and low output currents of 0.17mA (Low) and 1mA (High). It is housed in an SSON004R1010 package.

Feature Summary

• Nano Energy™ technology for ultra-low power consumption
• Adjustable reset delay time via external capacitor
