BD48K32G-TL

Overview

The BD48K32G-TL is a voltage detector from the ROHM BD48 series, designed for monitoring single power supply lines. It features a fixed threshold voltage of 3.2 V with an accuracy of ±1%. The device operates within a supply voltage range of 2.3 V to 6 V and supports a maximum input of 10 V. It utilizes an open-drain output type and includes a reset delay time of 100 µs. The component consumes 900 nA of operating current and functions across a temperature range of -40°C to +105°C. It is housed in an SSOP-3 package.

Feature Summary

• Provides precise voltage supervision with a fixed 3.2 V detection threshold and high accuracy.
• Features low power consumption suitable for battery-operated applications.
• Delivers reliable system resets through a dedicated open-drain output structure.

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered equipment needing under-voltage protection
• Embedded systems utilizing microcontrollers or logic circuits

Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm that the SSOP-3 package dimensions match your PCB footprint requirements. Ensure the 3.2 V threshold aligns with your specific circuit design needs. Check for moisture sensitivity handling instructions during storage and assembly processes.

Selection Notes

Select this component when a fixed 3.2 V threshold is required for single-input monitoring. Consider the SSOP-3 package for space-constrained designs. Evaluate the 900 nA current draw against system power budgets. Verify compatibility with the open-drain output interface used by the downstream logic.

Part Context

This part belongs to the BD48 series of supervisory circuits manufactured by ROHM Semiconductor. These components are specialized for power management ICs, focusing on voltage detection rather than complex regulation. The BD48K32G-TL variant specifically targets applications needing a 3.2 V reference point.

Replacement Considerations

BD5232G-1TR is listed as a recommended replacement with similar specifications, though it uses an SSOP5 package instead of SSOP3. Verify pinout compatibility and package size differences before substitution.
