BD4848G-TR

Overview

The BD4848G-TR is a standard CMOS voltage detector IC manufactured by ROHM Semiconductor. It features an under-voltage detection threshold of 4.8V with a precision of ±1%. The device operates within a reset active voltage range of 0.95V to 10V and utilizes an open-drain output type. Key electrical characteristics include a circuit current of 0.60μA (ON) and 0.85μA (OFF) at VS=4.8V, with hysteresis defined as VDET x 0.05. It lacks manual reset, watchdog timer, and automotive certification capabilities.

Feature Summary

• Standard CMOS voltage detection architecture
• Open-drain output configuration
• Low power consumption design

Applications

• General purpose voltage monitoring in electronic circuits
• System reset generation for microcontrollers
• Power supply supervision in consumer electronics

Procurement Notes

Verify the specific ordering suffix '-TR' corresponds to the taping package format required for your assembly process. Confirm that the 'Not Recommended for New Designs' status aligns with your product lifecycle requirements, as this component is intended for existing customer support rather than new development projects.

Selection Notes

Select this component when a fixed 4.8V detection threshold is required without additional features like watchdog timers or adjustable delays. Ensure the open-drain output compatibility matches the input requirements of the downstream logic. Consider the SSOP5 package dimensions for PCB layout constraints and verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the BD48 series of standard voltage detectors from ROHM Semiconductor. It is designed for general-purpose applications requiring reliable under-voltage detection. The series typically offers low current consumption and compact packaging options suitable for space-constrained designs.

Replacement Considerations

The BD5248G-1 is listed as a similar level replacement with the same package. Note that the BD5248G-1 includes an adjustable delay timer feature not present in the BD4848G-TR.
