BD5320NVX-2CTL

Overview

The BD5320NVX-2CTL is a CMOS reset IC from ROHM Semiconductor, designed for automotive applications. It features a detection voltage of 2V with ±2.5% precision and an adjustable reset delay timer controlled by an external capacitor. The device operates within a supply voltage range of 0.8V to 6V and maintains a low circuit current of 0.23µA (ON) and 0.27µA (OFF). It supports a CMOS output type with a low active state and functions reliably across a temperature range of -40°C to 125°C.

Feature Summary

• Nano Energy™ technology enables ultra-low power consumption suitable for battery-operated systems.
• Adjustable reset delay time allows customization via an external capacitor.
• Automotive-grade qualification ensures reliability under harsh environmental conditions.

Applications

• Microcontroller unit (MCU) reset circuits in automotive ECUs
• Voltage monitoring for battery management systems
• Power-on reset generation for embedded control modules

Procurement Notes

Verify the specific suffix 'NVX-2CTL' against the official datasheet to confirm package type SSON004R1010 and tape-and-reel packaging quantity. Ensure compatibility with AEC-Q100 Grade 1 requirements for your target automotive application segment before finalizing procurement specifications.

Selection Notes

Select this component when a precise 2V threshold is required for system supervision. The adjustable delay feature offers flexibility compared to fixed-delay alternatives. Consider the SSON004R1010 footprint constraints and the need for external timing capacitors during PCB layout design.

Part Context

This part belongs to the BD53xx series of Nano Energy™ CMOS reset ICs. It shares functional similarities with other models in the family but is distinguished by its specific 2V detection voltage and automotive-grade thermal rating. The NVX variant indicates a specific miniaturized surface-mount package configuration optimized for space-constrained designs.

Replacement Considerations

The BD5328G-2C is a similar CMOS output reset IC with a 2.8V detection voltage. Verify that the higher threshold does not compromise system safety margins if substituting directly.
