BD48E59G-TR

Overview

The BD48E59G-TR is a standard voltage detector IC from Rohm Semiconductor, featuring an N-channel open-drain output. It provides a typical under-voltage detection threshold of 5.9V with a precision of ±1%. The reset active state is low, and the device supports a reset active voltage range from 0.95V to 10V. It operates within a temperature range of -40°C to 105°C and consumes a circuit current of 0.60µA (ON) and 0.85µA (OFF) at Vs=4.8V. The hysteresis voltage is defined as VDET x 0.05. The component is housed in a 5-pin SSOP package.

Feature Summary

• High-accuracy voltage detection with ±1% precision for reliable system monitoring.
• Low current consumption design suitable for power-sensitive applications.
• N-channel open-drain output configuration for flexible interfacing.

Applications

• Processor supervisor circuits requiring precise voltage monitoring.
• Battery-powered devices needing low quiescent current supervision.
• General-purpose voltage detection in embedded systems.

Procurement Notes

Verify the specific suffix G-TR against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference the part number with official Rohm databases to confirm current supply status, as this series may have limited availability or obsolescence notices affecting long-term procurement planning.

Selection Notes

Select this component when a fixed 5.9V detection threshold is required without adjustable delay features. Compare circuit current requirements against alternatives like the BD52 series if lower power consumption is critical. Verify that the open-drain output capability meets the pull-up requirements of your target logic interface. Confirm that the operating voltage range covers your system's minimum and maximum supply variations.

Part Context

This part belongs to the BD48Exx series of highly accurate, low-current voltage detectors. The series includes various detection voltages ranging from 2.3V to 6.0V in 0.1V increments. These devices are designed for applications requiring simple, reliable supervision without complex timing features. The BD48E59G-TR specifically targets the 5.9V threshold niche within this family.
