BD48L26G-TL

Overview

The BD48L26G-TL is a voltage detector IC from the ROHM BD48 series, designed for monitoring single power supply rails. It features an N-channel open-drain output and operates within a supply voltage range of 0.95 V to 10 V. The device detects under-voltage conditions with a typical threshold of 2.6 V and maintains high accuracy of ±1%. It consumes low current, specified at 0.60 μA during operation and 0.85 μA in standby mode at VS=4.8 V. The component is housed in an SSOP-3 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides precise under-voltage detection with ±1% accuracy for reliable system supervision.
• Features ultra-low power consumption suitable for battery-operated applications.
• Utilizes an N-channel open-drain output interface for flexible logic integration.

Applications

• Portable electronic devices requiring extended battery life
• Microprocessor reset circuits in embedded systems
• Battery-powered instrumentation and sensors

Procurement Notes

Verify the specific suffix TL for tape-and-reel packaging configuration. Confirm RoHS compliance status through official documentation. Check for end-of-life notices as availability may be limited. Ensure compatibility with existing PCB footprint designs utilizing the SSOP-3 package dimensions.

Selection Notes

Select this component when a fixed 2.6 V threshold is required for under-voltage monitoring. Compare against the BD5226G-1 for alternative pinout or performance characteristics if needed. Consider the low quiescent current advantage over standard supervisors. Verify that the open-drain output meets the pull-up requirements of the target microcontroller input.

Part Context

This part belongs to the BD48xxx series of highly accurate, low-current voltage detectors. The series includes variants with different detection voltages and output types, such as the BD49xxx CMOS output family. The BD48L26G-TL specifically offers an open-drain output, distinguishing it from push-pull alternatives in broader PMIC catalogs.

Replacement Considerations

The BD5226G-1 is listed as a similar specification replacement option with comparable detection voltage and output type.
