BD5229NVX-2CTL

Overview

The BD5229NVX-2CTL is a Nano Energy™ CMOS voltage detector IC featuring adjustable delay time controlled by an external capacitor. It provides an N-channel open-drain output with a typical detection voltage of 2.9V and ±2.5% precision. The device operates within a reset active voltage range of 0.8V to 6V, consuming 0.23µA in the ON state and 0.27µA in the OFF state. It includes hysteresis of VDET x 0.05 and supports an L-output current of 1mA at low voltage. Qualified for automotive applications under AEC-Q100, it functions reliably from -40°C to 125°C.

Feature Summary

• Adjustable delay time setting via external capacitor
• Ultra-low current consumption suitable for battery-powered systems
• Automotive-grade reliability with functional safety support
• High-precision voltage detection with built-in hysteresis

Applications

• Microcontroller reset circuits requiring precise timing
• Battery-operated electronic devices needing power monitoring
• Automotive electronics systems demanding high reliability
• Logic circuit protection against undervoltage conditions

Procurement Notes

Verify the specific suffix NVX-2CTL corresponds to the SSON004R1010 package and 5000-unit taping quantity. Confirm AEC-Q100 qualification status for your specific automotive application requirements. Ensure the external capacitor selection aligns with the required delay time accuracy specifications across the operating temperature range. Check for any recent lifecycle notices regarding this specific variant.

Selection Notes

Select this component when an N-channel open-drain output is required for interfacing with various logic families. Choose the BD5229NVX-2CTL for its compact SSON004R1010 footprint compared to larger packages like SSOP5. Consider the adjustable delay feature if fixed-timer detectors do not meet system timing constraints. Evaluate the ultra-low standby current benefits for long-life battery applications.

Part Context

This part belongs to ROHM's Nano Energy™ series of CMOS voltage detectors designed for low-power applications. Unlike the older BD5229G series which uses SSOP5 packaging, this NVX variant utilizes a smaller SSON004R1010 package. It shares functional similarities with other BD52xx-2C models but offers improved integration and reduced board space requirements for modern compact designs.

Replacement Considerations

The BD5229G-2C is a pin-compatible alternative in SSOP5 packaging. For direct package replacement, verify availability of other BD5229NVX variants with different detection voltages if system requirements change.
