BD49E60G-TR

Overview

The BD49E60G-TR is a standard voltage detector from ROHM Semiconductor, designed for automotive applications with functional safety support. It features a typical under-voltage detection voltage of 6V and a precision of ±1%. The reset active voltage range spans from 0.95V to 10V. The device utilizes a CMOS output type without a manual reset or watchdog timer. Operating circuit current is 0.60µA at Vs=4.8V in the ON state and 0.85µA in the OFF state. Hysteresis voltage is defined as Vs multiplied by 0.05. The L output current is 0.4mA. The component is housed in an SSOP5 package and uses copper wire bonding technology.

Feature Summary

• Supports functional safety analysis for automotive use
• Features high precision voltage detection with ±1% accuracy
• Utilizes low-current CMOS output architecture
• Incorporates copper wire bonding for enhanced reliability

Applications

• Automotive electronic system monitoring
• Processor supervisor circuits
• Motor driver power supply monitoring

Procurement Notes

Verify the specific ordering suffix and packaging configuration against official documentation before procurement. Confirm that the functional safety classification aligns with project requirements. Ensure compatibility with the SSOP5 footprint and verify that the absence of a watchdog timer meets system design needs. Check for any end-of-life notices or recommended replacement parts if availability is constrained.

Selection Notes

Select this component when a fixed 6V detection threshold is required for automotive supervisory applications. The CMOS output is suitable for digital logic interfaces without additional pull-up components. Consider the low operating current for battery-powered systems. Verify that the 0.95V to 10V reset active range covers the intended supply voltage variations. Ensure the lack of manual reset functionality does not conflict with system recovery protocols.

Part Context

This part belongs to the BD49 series of highly accurate, low-current voltage detectors. The series offers various detection voltages in 0.1V increments. The BD49E60G-TR specifically targets the 6V detection point within this family. It shares common characteristics such as CMOS output and SSOP5 packaging with other variants in the series.

Replacement Considerations

BD5250G-1 is listed as a replacement with the same package but different output type (Open drain) and adjustable delay.
