BD48E47G-TR

Overview

The BD48E47G-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 detects specific voltages ranging from 2.3V to 6.0V in 0.1V increments. The device operates within a supply voltage range of 0.95V to 10V with a typical detection accuracy of ±1%. It includes hysteresis functionality defined as Vs x 0.05 and supports a reset active state of Low. The component is housed in a 5-pin SSOP package and is rated for operation between -40°C and +105°C.

Feature Summary

• High-accuracy voltage detection with ±1% precision
• Low current consumption suitable for battery-powered applications
• N-channel open-drain output configuration
• Integrated hysteresis to prevent output oscillation

Applications

• Processor supervisor circuits
• Battery voltage monitoring systems
• Portable electronic devices requiring power management

Procurement Notes

Verify the component status before procurement as this part may be designated as Not Recommended for New Designs or Last Time Buy. Confirm that the replacement BD5247G-1 meets all electrical requirements, particularly regarding reset delay timers and operating voltage ranges. Ensure the SSOP5 package dimensions are compatible with existing PCB footprints during the transition process.

Selection Notes

Select this component when precise voltage monitoring is required without manual reset capabilities. The BD48E47G-TR is suitable for designs needing a fixed 4.7V threshold with standard hysteresis. Consider the BD5247G-1 if adjustable delay timers or lower current consumption are necessary for the target application.

Part Context

This device belongs to the BD48xxx series of voltage detectors, which are designed for general-purpose supervision tasks. The series offers various detection voltages to accommodate different logic levels. The BD48E47G-TR specifically targets the 4.7V detection point within this family, providing a reliable solution for monitoring power rails in embedded systems.

Replacement Considerations

The BD5247G-1 is a recommended replacement with the same SSOP5 package. Note differences in reset delay timers and operating voltage ranges when substituting.
