BD48K25G-TL

Overview

The BD48K25G-TL is a single-channel voltage detector manufactured by Rohm Semiconductor, designed for supervisory circuit applications. It features an open-drain output and provides a reset signal with low active state logic. The device monitors input voltages with a typical threshold of 2.5V and maintains high accuracy within ±1%. It operates within a supply voltage range of 2.3V to 10V and supports a reset delay timer of 100 microseconds. The component functions reliably across a temperature range of -40°C to +105°C and is housed in a compact 3-SSOP package.

Feature Summary

• Provides precise under-voltage detection with a fixed threshold of 2.5V and ±1% accuracy.
• Features an open-drain output configuration suitable for interfacing with various digital logic families.
• Includes a built-in reset delay timer to ensure stable system initialization during power transitions.

Applications

• Portable electronic devices requiring reliable power monitoring
• Battery-operated equipment needing under-voltage protection
• General-purpose supervisory circuits in consumer electronics

Procurement Notes

Verify the specific suffix 'TL' to confirm the SSOP-3 packaging variant, as other suffixes may indicate different packages or tape types. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications. Check current supply status as this component may be subject to discontinuation or last-time-buy restrictions.

Selection Notes

Select this component when a fixed 2.5V threshold is required for single-input voltage monitoring. Ensure the open-drain output capability aligns with the pull-up requirements of your target logic interface. Consider the 100µs reset delay if immediate response is not critical for your application stability.

Part Context

This part belongs to the BD48Kxx series of standard voltage detectors from Rohm Semiconductor. It is functionally similar to the BD48K25G but specified with the TL ordering suffix indicating the specific reel or cut-tape packaging format. It serves as a dedicated power management IC for maintaining system integrity through voltage supervision.

Replacement Considerations

The BD5225G-1 is listed as a recommended replacement with similar specifications. Note that the BD5225G-1 utilizes an SSOP-5 package, which differs from the BD48K25G-TL's SSOP-3 footprint, requiring PCB layout adjustments for substitution.
