BD5227NVX-2CTL

Overview

The BD5227NVX-2CTL is a Nano Energy CMOS voltage detector IC manufactured by Rohm Semiconductor. It features an adjustable delay timer controlled by an external capacitor and utilizes an Nch open-drain output type. The device provides under-voltage detection with a typical threshold of 2.7V and offers high precision reset functionality. Designed for robust operation, it supports a wide operating temperature range from -40°C to 125°C. The component is housed in a compact SSON004R1010 package suitable for surface-mount applications.

Feature Summary

• Adjustable delay timer allows customization via external capacitor
• High-precision under-voltage detection with low power consumption
• Nch open-drain output configuration for flexible interface integration

Applications

• System reset circuits requiring precise timing control
• Battery-powered devices needing efficient power monitoring
• Automotive electronics requiring AEC-Q100 qualified components

Procurement Notes

Verify the specific suffix NVX-2CTL against the official Rohm datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the external capacitor selection aligns with the specified delay time calculations provided in the documentation. Confirm RoHS compliance status if required by the end-product regulations.

Selection Notes

Select this component when an adjustable reset delay is necessary rather than a fixed internal delay. Consider the Nch open-drain output capability for interfacing with various logic levels. Evaluate the thermal performance within the -40°C to 125°C range to ensure reliability in the target environment.
