BD45E235G-MTR

Overview

The BD45E235G-MTR is a fixed delay voltage detector manufactured by ROHM Semiconductor, designed for automotive applications. It features a threshold voltage of 2.3V with ±1% accuracy and a fixed reset delay time of 45ms. The device operates within a supply voltage range of 0.95V to 10V and consumes ultra-low current (0.80µA ON, 0.85µA OFF). It includes manual reset functionality and an open-drain output in an SSOP-5 package, certified under AEC-Q100.

Feature Summary

• Automotive-grade reliability with AEC-Q100 certification
• Ultra-low power consumption suitable for battery-backed systems
• Manual reset capability for system control flexibility
• Fixed delay timer eliminates external timing components

Applications

• Microprocessor reset circuits in automotive ECUs
• Battery backup monitoring systems
• Voltage supervision for embedded controllers

Procurement Notes

Verify the specific suffix 'MTR' against the official datasheet to confirm tape-and-reel packaging specifications. Confirm that the component meets the required AEC-Q100 qualification standards for your target automotive application. Ensure compatibility with the SSOP-5 footprint during PCB layout verification.

Selection Notes

Select this component when a precise 2.3V threshold and fixed 45ms delay are required without external capacitors. Consider the manual reset feature if system initialization control is necessary. Verify that the open-drain output interface matches the input requirements of the monitored microcontroller or logic circuit.

Part Context

This part belongs to the BD45ExxxG-M series of fixed delay voltage detectors. It shares the SSOP-5 package and low-power architecture with other variants in the family, differing primarily in threshold voltage settings. The series is optimized for automotive environments requiring high reliability and minimal standby current.

Replacement Considerations

BD45235G-TR is listed as a parameter-equivalent alternative. Verify pinout compatibility and ensure the replacement meets the same AEC-Q100 automotive qualification requirements before substitution.
