BD48K30G-TL

Overview

The BD48K30G-TL is a standard voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It features a fixed threshold detection voltage of 3.0 V with a precision accuracy of ±1%. The device operates within a supply voltage range of 2.3 V to 10 V and consumes a typical operating current of 900 nA. It provides an open-drain output type with a reset delay time of 100 us. The component is housed in an SSOP-3 package and supports an extended industrial temperature range from -40°C to +105°C.

Feature Summary

• Provides precise voltage monitoring with a fixed 3.0 V detection threshold and high accuracy.
• Features ultra-low power consumption suitable for battery-operated systems.
• Delivers reliable system reset via open-drain output with defined delay characteristics.

Applications

• Portable electronic devices requiring low-power supervision
• Battery-powered equipment needing under-voltage protection
• General-purpose microprocessor reset circuits

Procurement Notes

Verify the specific ordering suffix TL against official documentation to ensure correct packaging configuration. Confirm that the SSOP-3 package dimensions align with your PCB footprint requirements. Check for any moisture sensitivity level restrictions during storage and handling. Ensure compatibility with your assembly process temperatures given the industrial grade rating.

Selection Notes

Select this component when a fixed 3.0 V threshold is required for single-input voltage monitoring. Consider the SSOP-3 package size constraints and the open-drain output capability for interfacing with various logic levels. Evaluate the 900 nA quiescent current against system power budgets. Verify that the absence of manual reset or watchdog functions meets the design simplicity needs.

Part Context

This part belongs to the BD48 series of standard voltage detectors from ROHM Semiconductor. It is categorized under PMIC - Power Management ICs and specifically Supervisory Circuits. The series offers various threshold voltages to accommodate different rail monitoring needs across consumer and industrial electronics.

Replacement Considerations

BD5230G-1TR is listed as a recommended replacement with similar specifications. Note that the substitute uses an SSOP5 package instead of SSOP3, requiring layout adaptation.
