BD48K41G-TL

Overview

The BD48K41G-TL is a voltage detector IC from ROHM Semiconductor featuring an N-channel open-drain output. It provides a detection threshold of 4.1 V with a reset delay time of 100 µs. The device operates within a supply voltage range of 2.3 V to 6.0 V and supports a maximum operating voltage of 10 V. It functions across a temperature range of -40 °C to +105 °C, consumes 900 nA of current, and utilizes an SSOP-3 package.

Feature Summary

• Provides high-accuracy voltage monitoring with a fixed detection threshold.
• Features an N-channel open-drain output for direct interface with logic circuits.
• Includes a built-in reset delay timer to ensure stable power-up sequences.
• Designed for low-current operation suitable for battery-powered applications.

Applications

• Processor supervisor circuits requiring precise voltage monitoring
• Battery-operated electronic devices needing power management
• Embedded systems utilizing CMOS logic interfaces

Procurement Notes

Verify the specific suffix 'TL' corresponds to the tape and reel packaging format required for your assembly line. Confirm that the SSOP-3 pinout orientation matches your PCB footprint design. Ensure the component meets RoHS compliance standards for your target market regulations before finalizing procurement orders.

Selection Notes

Select this component when a fixed 4.1 V threshold is required for system supervision. The open-drain output allows flexible interfacing with various logic families. Consider the 100 µs reset delay for timing requirements during power transitions. Verify that the 900 nA quiescent current fits within the system's power budget constraints.

Part Context

This part belongs to the BD48xxx series of highly accurate, low-current voltage detectors. The series offers various detection voltages in 0.1 V increments. The BD48K41G-TL specifically targets applications needing a 4.1 V trip point with minimal power consumption and compact surface-mount packaging.

Replacement Considerations

The BD5241G-1TR is listed as a recommended replacement with similar specifications. Note that the substitute uses an SSOP-5 package instead of SSOP-3, requiring layout adjustments. The replacement features adjustable delay capabilities unlike the fixed delay of the original part.
