BD48L58G-TL

Overview

The BD48L58G-TL is a voltage detector IC from ROHM Semiconductor's BD48xxx series, designed for monitoring single-input supply voltages. It features an N-channel open-drain output and operates within a maximum supply voltage of 10 V. The device detects under-voltage conditions with a typical threshold of 5.8 V and maintains high accuracy of ±1%. It consumes low current, specified at 900 nA during operation, and includes a fixed reset delay time of 100 µs. The component supports an operating temperature range from -40 °C to +105 °C and is housed in a compact SSOP-3 package.

Feature Summary

• Provides precise voltage supervision with high detection accuracy for system reliability
• Utilizes an N-channel open-drain output interface for flexible logic integration
• Designed for ultra-low power consumption suitable for battery-operated applications

Applications

• Processor supervisor circuits requiring stable voltage monitoring
• Battery-powered devices needing low quiescent current management
• Industrial control systems operating across extended temperature ranges

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details via official datasheets. Check humidity sensitivity handling requirements during storage and assembly. Ensure replacement strategies account for discontinued availability. Validate pinout compatibility if substituting with similar family members.

Selection Notes

Select this part when a fixed 5.8 V detection threshold is required. Consider the SSOP-3 package constraints for PCB layout. Evaluate the open-drain output capability against load requirements. Assess the 100 µs reset delay against system startup timing needs. Verify that the 10 V maximum input rating exceeds the application's peak voltage.

Part Context

This component belongs to the BD48xxx series of highly accurate, low-current voltage detectors. The series distinguishes itself by offering specific detection voltages in 0.1 V increments. Unlike the BD49xxx variants which feature CMOS outputs, the BD48xxx line provides N-channel open-drain outputs. This specific model represents the 5.8 V threshold option within that lineup.

Replacement Considerations

BD48L56G-TL offers a 5.6 V threshold with identical packaging and electrical characteristics. BD48L59G-TL provides a 5.9 V threshold as an alternative. Both share the same SSOP-3 form factor and open-drain output structure.
