BD48K27G-TL

Overview

The BD48K27G-TL is a high-precision voltage detector IC from the ROHM BD48xxx series, designed for monitoring power supply voltages. It features an N-channel open-drain output and provides a typical under-voltage detection threshold of 2.7V with ±1% precision. The device operates within a reset active voltage range of 0.95V to 10V and includes no manual reset or watchdog timer functions. It is housed in a compact SSOP3 package and supports a minimum packing quantity of 3000 units in tape-and-reel packaging.

Feature Summary

• High-precision voltage detection with ±1% accuracy tolerance
• N-channel open-drain output configuration for flexible interfacing
• Low current consumption characteristics suitable for battery-powered applications
• Compact SSOP3 surface-mount package design

Applications

• Processor supervisor circuits requiring precise voltage monitoring
• Battery-operated devices needing low quiescent current supervision
• General-purpose power supply voltage detection systems

Procurement Notes

Verify the specific suffix TL indicates tape-and-reel packaging when sourcing. Confirm the SSOP3 package variant matches your PCB footprint requirements. Check RoHS compliance status against current regulatory standards for your target market. Ensure the component availability aligns with production timelines as supply status may vary by region.

Selection Notes

Select this component when a fixed 2.7V detection threshold is required without manual reset capabilities. The open-drain output allows for wired-OR connections and compatibility with various logic levels. Consider the SSOP3 package size constraints and ensure adequate thermal dissipation within the specified operating temperature range for reliable performance.

Part Context

This part belongs to the BD48xxx series of voltage detectors, which are characterized by high accuracy and low current consumption. The series offers multiple detection voltages ranging from 2.3V to 6.0V in 0.1V increments. The BD48K27G-TL specifically targets applications requiring a 2.7V threshold with standard open-drain output functionality.

Replacement Considerations

The BD5227G-1 is listed as a similar specification replacement option. Verify pinout compatibility and electrical parameter alignment before substitution. Note that the BD5227G-1 may have different package options such as SSOP5.
