BD48L30G-TL

Overview

The BD48L30G-TL is a high-precision, low-current voltage detector IC from the ROHM BD48xxx series. It features an N-channel open-drain output and provides a fixed detection voltage of 3.0V with ±1% precision. The device operates within a reset active voltage range of 0.95V to 10V and consumes minimal current (0.60μA ON, 0.85μA OFF at Vs=4.8V). It includes hysteresis defined as Vs x 0.05 and functions in temperatures from -40°C to 105°C. Packaged in SSOP3, it lacks delay timers or manual reset features.

Feature Summary

• High-precision voltage monitoring with ±1% detection accuracy
• Ultra-low power consumption suitable for battery-operated systems
• N-channel open-drain output for flexible logic interfacing
• Integrated hysteresis to prevent output oscillation during threshold transitions

Applications

• Processor supervisor circuits requiring stable voltage monitoring
• Battery-powered portable devices needing extended operational life
• Embedded systems utilizing low-voltage detection thresholds

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions. Ensure storage conditions comply with moisture sensitivity levels specified in the manufacturing documentation to maintain reliability.

Selection Notes

Select this component when a precise 3.0V threshold is required without additional timing functions. Consider the SSOP3 package constraints for PCB layout. Evaluate if the absence of a reset delay timer meets system stability requirements. Compare against newer alternatives like the BD5230G-1 if adjustable delays or lower current consumption are necessary for the specific application design.

Part Context

This part belongs to the BD48xxx series of voltage detectors, characterized by high accuracy and low current draw. The series offers various detection voltages from 2.3V to 6.0V in 0.1V increments. All devices in this family share similar architectural features, including N-channel open-drain outputs and compact packaging options designed for space-constrained electronic designs.

Replacement Considerations

The BD5230G-1 is listed as a recommended replacement with similar specifications. Note that the substitute uses an SSOP5 package instead of SSOP3, requiring PCB footprint adaptation. The replacement offers adjustable delay timers and slightly improved current efficiency.
