BD48K26G-TL

Overview

The BD48K26G-TL is a high-accuracy, low-current voltage detector IC from the ROHM BD48xxx series. It features an N-channel open-drain output and monitors a single input voltage with a typical threshold of 2.6V. The device operates within a supply voltage range of 0.95V to 10V and offers detection voltages from 2.3V to 6.0V in 0.1V increments. Key electrical parameters include a reset delay time of 100µs, accuracy of ±1%, and a maximum operating temperature of +105°C. It consumes approximately 900nA of operating current.

Feature Summary

• Provides precise voltage monitoring with high accuracy for system supervision
• Features ultra-low current consumption suitable for battery-powered applications
• Utilizes an N-channel open-drain output for flexible logic interfacing

Applications

• Processor supervisor circuits requiring reliable reset signals
• Battery-operated devices needing low quiescent current monitoring
• General-purpose voltage level detection in embedded systems

Procurement Notes

Verify the specific suffix G-TL against official ROHM documentation to confirm package type and tape-and-reel specifications. Confirm availability status as distribution listings may indicate end-of-life or limited stock conditions. Ensure compatibility with your manufacturing process regarding moisture sensitivity levels and reflow soldering profiles before procurement.

Selection Notes

Select this component when a fixed 2.6V threshold is required for under-voltage detection. Consider the SSOP-3 package for space-constrained designs. Evaluate the 100µs reset delay against system timing requirements. Compare power consumption needs against other family members if lower current is critical, noting that some variants offer reduced standby currents.

Part Context

This part belongs to the BD48xxx series of voltage detectors, which are designed for high precision and low power consumption. The series includes various detection voltages and output types, such as CMOS outputs in the BD49xxx counterpart. The BD48K26G-TL specifically targets applications requiring stable supervision with minimal impact on system power budgets.

Replacement Considerations

Check for direct substitutes like BD48K26G without the TL suffix if reel packaging is not required. Verify functional equivalence with BD48L26G-TL if package differences are acceptable. Consult ROHM datasheets for pin-compatible alternatives within the same voltage threshold family.
