BD48K44G-TL

Overview

The BD48K44G-TL is a voltage detector IC from the BD48xxx series by ROHM Semiconductor. It features an N-channel open-drain output and provides a fixed detection threshold of 4.4V. The device operates within a supply voltage range of 0.95V to 10V, with a reset delay time of 100µs. It maintains high accuracy with a detection voltage tolerance of ±1% and consumes low current, typically 0.6µA at 4.8V. The component is housed in a compact SSOP-3 package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• High-precision voltage monitoring with ±1% detection accuracy
• Ultra-low power consumption suitable for battery-operated systems
• N-channel open-drain output for flexible logic interfacing
• Compact three-pin surface-mount packaging

Applications

• Processor supervisor circuits requiring precise voltage monitoring
• Battery-powered portable devices needing low quiescent current
• Embedded systems utilizing standard voltage thresholds
• General-purpose voltage detection in industrial control units

Procurement Notes

Verify the specific suffix TL indicates tape and reel packaging configuration. Confirm RoHS compliance status through official datasheets. Check for moisture sensitivity level requirements during storage and handling. Ensure the SSOP-3 footprint matches PCB design constraints. Validate that the 4.4V threshold aligns with target system voltage levels.

Selection Notes

Select this component when a fixed 4.4V threshold is required without adjustable settings. Consider the open-drain output capability for compatibility with various logic families. Evaluate the low current consumption against strict power budget constraints. Compare the SSOP-3 package size against available board space limitations. Verify operational temperature range suitability for the intended environment.

Part Context

This part belongs to the BD48xxx series of voltage detectors, which offers multiple fixed threshold options ranging from 2.3V to 6.0V in 0.1V increments. The series shares common characteristics including low current operation and open-drain outputs. The BD48K44G-TL specifically targets applications requiring a 4.4V detection point within this standardized family lineup.

Replacement Considerations

BD5244G-1TR is listed as a similar specification replacement option. Note that the substitute uses a different SSOP-5 package compared to the original SSOP-3. Verify pinout compatibility and electrical parameter alignment before substitution.
