BD52E30G-TR

Overview

The BD52E30G-TR is a voltage detector IC from ROHM Semiconductor, designed for monitoring power supply voltages. It features a typical threshold voltage of 3.0V with ±1% precision. The device operates within a reset active voltage range of 0.95V to 10V and supports an adjustable reset delay timer. It utilizes an open-drain output type and consumes a circuit current of 0.85µA at Vdet=4.8V. The component is housed in an SSOP-5 package and is rated for automotive applications with functional safety support.

Feature Summary

• Supports automotive functional safety analysis
• Features adjustable reset delay timer
• Provides high-precision voltage detection

Applications

• Automotive electronic systems
• Power supply monitoring circuits
• Voltage supervision in embedded devices

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official documentation. Check for end-of-life or not-for-new-design (NRND) status as indicated by related model variants. Ensure the SSOP-5 package matches PCB footprint requirements. Validate automotive qualification data if required for the target application.

Selection Notes

Select this component when a 3.0V threshold with high accuracy is required for automotive-grade voltage monitoring. Consider the open-drain output compatibility with system logic levels. Evaluate the need for adjustable delay functionality versus fixed delay alternatives. Verify that the 0.85µA standby current meets low-power design constraints. Ensure the SSOP-5 package fits the available board space.

Part Context

This part belongs to the BD52(53)ExxG series of voltage detectors. It is specifically engineered for automotive use cases requiring functional safety support. The series offers various threshold voltages and output configurations. The BD52E30G-TR represents the 3.0V threshold variant with adjustable delay capabilities.

Replacement Considerations

Check for direct substitutes within the BD52 series with different thresholds. Verify availability of alternative packages if SSOP-5 is constrained. Review updated datasheets for any pin-compatible upgrades.
