BD48E52G-TR

Overview

The BD48E52G-TR is a standard CMOS voltage detector IC from the BD48xxx series by Rohm Semiconductor. It features an N-channel open-drain output and provides under-voltage detection at a typical threshold of 5.2V with ±1% precision. The device operates within a reset active voltage range of 0.95V to 10V and consumes ultra-low circuit current, specified as 0.60µA (ON) and 0.85µA (OFF) at Vs=4.8V. It includes hysteresis set at Vs x 0.05 and supports an operating temperature range from -40°C to 105°C. Packaged in SSOP5, it utilizes Cu wire bonding and holds AEC-Q100 automotive grade certification.

Procurement Notes

Verify the specific suffix G-TR confirms the SSOP5 tape-and-reel packaging configuration. Confirm RoHS3 compliance status for environmental regulations. Ensure the part number matches the exact 5.2V detection threshold required for the design. Check for any obsolescence notices or last-time-buy statuses associated with this specific revision.

Selection Notes

Select this component when a precise 5.2V detection threshold is required for automotive applications. The N-channel open-drain output suits interfacing with various logic levels. Consider the low current consumption for battery-operated systems. Verify that the SSOP5 package dimensions fit the PCB layout constraints compared to alternative packages like SOT-23-5.

Part Context

This part belongs to the BD48Exx family of high-accuracy, low-current voltage detectors. The series offers multiple detection voltages from 2.3V to 6.0V in 0.1V increments. It is designed for robust performance in harsh environments, featuring wide operating temperature ranges and automotive qualification. The family shares common electrical characteristics but varies in detection thresholds and output types.

Replacement Considerations

BD48E52G-MTR is a parameter-equivalent alternative with identical electrical specifications. BD52E52G-TR offers similar functionality but may differ in package or specific automotive qualification details. Verify pin compatibility and detection voltage tolerance before substitution.
