BD48K54G-TL

Overview

The BD48K54G-TL is a high-accuracy, low-current voltage detector IC from the ROHM BD48xxx series. 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 has a detection voltage of 5.4V with ±1% accuracy. It operates within a supply voltage range of 0.95V to 10V. The reset delay time is 100µs. The maximum operating temperature is +105°C, and the minimum is -40°C. The circuit current is typically 0.60µA (ON) and 0.85µA (OFF) at Vs=4.8V. Hysteresis is Vs x 0.05. It is housed in an SSOP-3 package.

Procurement Notes

Verify the exact part number BD48K54G-TL against official ROHM documentation to confirm specifications. Check for obsolescence status as some similar parts are marked obsolete. Ensure the SSOP-3 package matches your PCB footprint. Confirm RoHS compliance requirements for your manufacturing process. Validate the 5.4V detection threshold meets your system design needs before procurement.

Selection Notes

Select this component when a precise 5.4V detection threshold is required. Consider the ±1% accuracy for critical voltage monitoring tasks. The low current draw makes it suitable for energy-efficient designs. Ensure the 100µs reset delay fits your system timing constraints. Verify the SSOP-3 package availability for your assembly line.

Part Context

The BD48K54G-TL belongs to the BD48xxx series of voltage detectors. This series offers various detection voltages from 2.3V to 6.0V. The family shares common features like low current consumption and open-drain outputs. Other variants include BD48K36G-TL and BD48K48G-TL.
