BD48E54G-TR

Overview

The BD48E54G-TR is a high-accuracy, low-current voltage detector IC from the BD48xxx series by ROHM Semiconductor. It features an N-channel open-drain output and provides a specific detection voltage of 5.4V. The device operates within a supply voltage range up to 10V and offers reset delay times of 100µs or 200ms. It is designed for applications requiring precise monitoring with minimal power consumption.

Feature Summary

• High accuracy voltage detection with N-channel open-drain output
• Low current consumption suitable for battery-powered systems
• Fixed detection voltage options in 0.1V increments

Applications

• Processor supervisor circuits
• Battery voltage monitoring
• Power management system supervision

Procurement Notes

Verify the exact detection voltage (5.4V) and package type (SSOP-5) against your schematic requirements. Confirm that the N-channel open-drain output configuration matches your pull-up resistor design. Check for any specific ordering suffixes that might indicate different packaging or temperature grades if available in official documentation.

Selection Notes

Select this component when a fixed 5.4V threshold is required for system supervision. Ensure the application can accommodate the open-drain output structure. Consider the low current draw benefits for energy-sensitive designs. Verify compatibility with the target microcontroller's input voltage levels.

Part Context

This part belongs to the BD48xxx series of voltage detectors, which are characterized by high precision and low power consumption. The series includes various detection voltages ranging from 2.3V to 6.0V. These ICs are commonly used in embedded systems where reliable power monitoring is critical for proper operation and safety.

Replacement Considerations

Check for other parts in the BD48xxx series with similar detection voltages if 5.4V is not strictly mandatory. Verify pinout compatibility with alternative supervisors from ROHM or other manufacturers. Ensure electrical specifications such as reset delay and operating voltage range meet system requirements.
