BD5225G-2MTR

Overview

The BD5225G-2MTR is a Nano Energy™ CMOS voltage detector IC designed for automotive applications, featuring AEC-Q100 Grade 1 qualification. It provides a fixed threshold detection voltage of 2.5V with ±2.5% precision. The device operates within a supply voltage range of 0.8V to 6.0V and draws a typical operating current of 230nA. Reset delay time is adjustable via an external capacitor, with a typical default delay of 55.5ms. It utilizes an N-channel open-drain output and functions across a temperature range of -40°C to +105°C.

Feature Summary

• Adjustable reset delay timer controlled by an external capacitor
• High-precision voltage detection with ±2.5% accuracy
• Ultra-low power consumption suitable for battery-operated systems
• Automotive-grade reliability with AEC-Q100 certification

Applications

• Microprocessor system supervision in automotive electronics
• Battery voltage monitoring in electric vehicles
• Power-on reset generation for embedded controllers

Procurement Notes

Verify the specific suffix '2MTR' confirms the SSOP-5 package and tape-and-reel packaging format. Confirm AEC-Q100 Grade 1 compliance requirements match your system's functional safety standards. Ensure the external capacitor selection aligns with the desired reset delay tolerance specifications provided in the official datasheet.

Selection Notes

Select this component when a fixed 2.5V threshold is required with customizable reset timing. Compare against BD52xx series variants if different detection voltages or CMOS outputs are needed. Consider the SSOP-5 footprint constraints and verify thermal performance within the -40°C to +105°C operational range for your specific enclosure design.

Part Context

This part belongs to ROHM's Nano Energy™ family of low-power voltage detectors. The BD52xx-2M series specifically offers N-channel open-drain outputs with externally adjustable delay times. It complements the BD53xx series which provides CMOS outputs, offering flexibility for various logic interface requirements in automotive and industrial power management designs.

Replacement Considerations

BD52E25G-MTR is listed as a parameter-equivalent alternative, though it carries an 'Not Recommended for New Designs' status. Verify pinout compatibility and electrical specifications before substitution.
