BD5210G-2MTR

Overview

The BD5210G-2MTR is a voltage detector IC from ROHM Semiconductor, designed for automotive applications with AEC-Q100 qualification. It features a fixed threshold voltage of 1 V and an adjustable reset delay timer. The device operates within a supply voltage range of 0.8 V to 7 V and delivers high accuracy with a detection precision of ±2%. It utilizes an open-drain output type and consumes low power, with circuit currents of 0.23 µA (ON) and 0.27 µA (OFF). The component is housed in an SSOP-5 package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Adjustable reset delay timer allows customization via external capacitor
• High detection accuracy with ±2% precision across the operating temperature range
• Low power consumption suitable for battery-operated systems
• Automotive grade reliability certified under AEC-Q100 standards

Applications

• Automotive electronic control unit monitoring

Procurement Notes

Verify the specific suffix '2M' corresponds to the open-drain output variant when sourcing. Confirm that the SSOP-5 package dimensions match your PCB footprint requirements. Ensure the selected distributor provides valid RoHS compliance documentation. Check for functional safety support status if integrating into safety-critical automotive designs. Validate the operating temperature range against your system's environmental specifications.

Selection Notes

Select this component when a fixed 1 V threshold is required for system supervision. Choose the open-drain output configuration if interfacing with various logic levels. Consider the adjustable delay feature if noise immunity during power-up is critical. Compare current consumption metrics against other nano-energy series options if battery life is a primary constraint. Verify compatibility with existing layout constraints due to the compact SSOP-5 package.

Part Context

This part belongs to the BD52xxG-M series of CMOS reset ICs developed by ROHM Semiconductor. The series integrates high-precision voltage detection with adjustable delay circuits using CMOS technology. It is positioned as a nano-energy solution for power management, offering flexibility through external component tuning while maintaining automotive-grade durability and small form factors.

Replacement Considerations

BD5210G-1TR offers similar functionality but with different packaging or minor parameter variations; verify pinout compatibility. BD5213G-2MTR provides a higher threshold voltage of 1.3 V, requiring circuit adjustment. BD52E40G-M is an obsolete alternative with adjustable delay but different electrical characteristics.
