BD4860G-TR

Overview

The BD4860G-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features an under-voltage detection threshold of 6.0 V with a precision of ±1%. The device operates within a reset active voltage range of 0.95 to 10 V and utilizes an open-drain output type. Key electrical characteristics include a circuit current of 0.60 μA (ON) and 0.85 μA (OFF) at Vs=4.8V. It employs hysteresis defined as Vs x 0.05 and supports L output currents of 0.4 mA (LowVol) and 2 mA (HighVol). The component is housed in an SSOP5 package and functions across a temperature range of -40°C to 105°C.

Feature Summary

• Provides precise under-voltage detection with a typical threshold of 6.0 V and ±1% accuracy.
• Features an open-drain output configuration suitable for interfacing with various logic families.
• Incorporates internal hysteresis to prevent output oscillation during voltage transitions near the detection threshold.

Applications

• Monitoring power supply rails in embedded systems
• Reset generation for microcontrollers and digital logic circuits
• Battery-powered devices requiring low standby current

Procurement Notes

Verify the specific ordering suffix and packaging details against the latest manufacturer documentation before procurement. Confirm that the supply status aligns with project requirements, as this component may be subject to end-of-life or last-time-buy restrictions. Ensure compatibility with existing PCB footprints and thermal management strategies during integration.

Selection Notes

Select this component when a fixed 6.0 V detection threshold is required for system supervision. Consider the open-drain output capability for level shifting applications. Evaluate the low operating current for battery-sensitive designs. Verify that the SSOP5 package dimensions fit the available board space and that the temperature range meets environmental specifications.
