BD48K50G-TL

Overview

The BD48K50G-TL is a standard voltage detector IC from ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features an N-channel open-drain output and operates within a detection voltage range of 2.3V to 6.0V, with a specific threshold of 5.0V for this variant. The device supports a maximum operating voltage of 10V and maintains high accuracy with a typical detection precision of ±1%. It functions reliably across an extended temperature range from -40°C to +105°C, consuming low quiescent current.

Feature Summary

• Provides precise under-voltage detection with a fixed 5.0V threshold and ±1% accuracy.
• Features an N-channel open-drain output for direct interface with digital logic systems.
• Operates with minimal power consumption, suitable for battery-powered applications.
• Ensures stable performance across industrial temperature ranges without requiring manual reset.

Applications

• Processor supervisor circuits requiring reliable power-on reset signals.
• Battery-operated devices needing low-quiescent current monitoring.
• Industrial control systems utilizing wide temperature range components.
• General-purpose voltage supervision in embedded electronics.

Procurement Notes

Verify the ordering part number BD48K50G-TL against the specific package requirements, as the base model BD48K50G may refer to different packaging configurations. Confirm RoHS compliance status and check for any last-time-buy notices or end-of-life declarations directly with the manufacturer or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when a fixed 5.0V detection threshold is required with high precision. Ensure the application environment stays within the -40°C to +105°C operating range. Verify that the open-drain output configuration matches the downstream circuit's pull-up requirements. Consider the SSOP-3 package dimensions for PCB layout constraints.

Part Context

This part belongs to the BD48xxx series of highly accurate, low-current voltage detectors. The series offers various detection voltages from 2.3V to 6.0V in 0.1V increments. These ICs are designed for general-purpose voltage monitoring in consumer and industrial electronics, providing a compact solution for power management tasks.

Replacement Considerations

BD5250G-1TR is listed as a recommended replacement with similar specifications, though it uses an SSOP-5 package instead of SSOP-3. Verify pinout compatibility and electrical parameter alignment before substitution.
