BD48K28G-TL

Overview

The BD48K28G-TL is a voltage detector IC from the BD48xxx series, designed for processor supervision. It features an N-channel open-drain output and operates within a supply voltage range of 2.3V to 10V. The device detects voltages with high accuracy, offering a specific detection threshold of 2.8V. It includes a reset delay timer of 100us and maintains low current consumption at 900nA. The component is housed in an SSOP-3 package and functions reliably across temperatures from -40°C to +105°C.

Feature Summary

• Provides precise voltage monitoring with high detection accuracy for system stability.
• Utilizes an N-channel open-drain output interface for flexible logic integration.
• Ensures reliable operation through a dedicated reset delay timer mechanism.

Applications

• Processor supervisor circuits
• Voltage monitoring in embedded systems
• Power management supervision

Procurement Notes

Verify the exact part number BD48K28G-TL against official ROHM Semiconductor documentation to confirm specifications. Check current availability status as distribution channels may indicate limited stock or end-of-life conditions. Ensure compatibility with required operating temperatures and voltage thresholds before procurement.

Selection Notes

Select this component when a fixed 2.8V detection threshold is required for single-input voltage monitoring. Consider the SSOP-3 package size constraints and the need for an open-drain output configuration. Evaluate the 100us reset delay requirement against system timing needs.

Part Context

This device 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, all sharing similar low-power characteristics and open-drain output structures for standardized design implementation.

Replacement Considerations

Consult official manufacturer substitution guides for compatible alternatives. Verify that any replacement matches the 2.8V threshold, SSOP-3 package, and electrical performance requirements.
