BD48K35G-TL

Overview

The BD48K35G-TL is a voltage detector IC from the BD48 series by ROHM Semiconductor. It features an N-channel open-drain output and a detection threshold of 3.5 V with ±1% precision. The device operates within a supply voltage range of 0.95 V to 10 V and supports a reset active state of Low. It consumes 0.60 μA in the ON state and 0.85 μA in the OFF state at Vs=4.8V. The component is housed in an SSOP-3 package, operates from -40°C to +105°C, and has a maximum power dissipation of 700 mW.

Feature Summary

• Provides high-accuracy voltage monitoring with ±1% detection threshold precision.
• Features low current consumption for efficient power management in battery-operated systems.
• Utilizes an N-channel open-drain output interface for flexible logic integration.

Applications

• Processor supervisor circuits requiring precise voltage monitoring

Procurement Notes

Verify the specific ordering part number BD48K35G-TL against the manufacturer's latest documentation to confirm current supply status. Ensure compatibility with the SSOP-3 package dimensions and thermal requirements. Confirm RoHS compliance and lead-free status if required by your manufacturing standards. Cross-reference the detection voltage and output characteristics with your system design specifications before finalizing procurement.

Selection Notes

Select this component when a fixed 3.5 V detection threshold with high accuracy is required. Consider the low current consumption for applications where power efficiency is critical. Ensure the operating temperature range meets your environmental conditions. Verify that the open-drain output configuration aligns with your downstream circuitry requirements.

Part Context

The BD48K35G-TL belongs to the BD48xxx series of voltage detectors, which are designed for high accuracy and low current consumption. This series offers various detection voltages in 0.1 V increments.

Replacement Considerations

BD5235G-1 is listed as a recommended replacement with similar specifications. Note that the replacement uses an SSOP-5 package instead of SSOP-3, requiring layout adjustments. The detection voltage remains 3.5 V, but precision and current consumption values differ slightly.

FAQ

What is the reset active state of the BD48K35G-TL?

The reset active state is Low, indicating that the output goes low when the monitored voltage drops below the detection threshold.

Does the BD48K35G-TL include a manual reset function?

No, the BD48K35G-TL does not have a manual reset feature; it relies solely on the monitored voltage level for resetting.
