BD52E24G-MTR

Overview

The BD52E24G-MTR is a voltage detector IC designed for automotive applications, featuring an adjustable reset delay timer controlled by an external capacitor. It operates within a supply voltage range of 0.95 V to 10 V with a typical detection threshold of 2.4 V and ±1% precision. The device draws 0.85 µA in both ON and OFF states at VDET=4.8V and includes hysteresis equal to 5% of the detection voltage. Packaged in SSOP-5, it meets AEC-Q100 standards and supports functional safety analysis.

Feature Summary

• Adjustable reset delay time controlled via external capacitor connection
• High accuracy voltage detection with ±1% precision tolerance
• Automotive-grade reliability compliant with AEC-Q100 qualification
• Low power consumption suitable for battery-backed systems

Applications

• Automotive electronic control unit (ECU) power monitoring
• Battery voltage supervision in electric vehicles
• System reset generation for microcontrollers under low voltage conditions
• Functional safety support circuits in automotive modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and AEC-Q100 certification status prior to integration. Ensure design-in compatibility with existing SSOP-5 footprints and validate external capacitor selection for required delay timing specifications.

Selection Notes

Select this component when adjustable delay functionality is required for precise system reset sequencing. Consider the 0.95 V minimum operating voltage and 10 V maximum limit against target supply rails. Evaluate thermal performance within the -40°C to 105°C range for automotive environment suitability.

Part Context

Part of Rohm's BD52E series voltage detectors optimized for automotive use. Designed to replace legacy components while offering enhanced delay adjustability. Manufactured using Cu wire bonding technology for improved reliability. Intended for high-volume automotive production lines requiring consistent performance across temperature variations.

Replacement Considerations

BD52E25G-MTR offers similar features with a 2.5 V detection threshold instead of 2.4 V. Verify threshold compatibility before substitution. No other direct pin-to-pin replacements are documented in official sources.
