BD82039FVJ-GE2

Power Distribution Switches, Load Drivers Overview

The BD82039FVJ-GE2 is a high-side power switch IC from Rohm Semiconductor designed for load distribution applications. It features three independent output channels with a maximum continuous current limit of 600 mA per channel. The device operates within a supply voltage range of 2.7 V to 5.5 V and utilizes an N-channel MOSFET structure. Key electrical parameters include a maximum on-resistance of 90 mΩ, a maximum turn-on time of 20 ms, and a maximum idle time of 20 µs. It functions reliably across an operating temperature range of -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates three high-side switching channels controlled by active-low logic inputs.
• Provides comprehensive protection including fixed current limiting, thermal shutdown, reverse current protection, and under-voltage lockout.
• Features an open-drain fault flag output to indicate over-current or thermal events.
• Includes soft-start circuitry to manage inrush currents during activation.

Power Distribution Switches, Load Drivers Applications

• USB port power management and distribution
• General-purpose load switching in consumer electronics
• Peripheral device power control in embedded systems

Power Distribution Switches, Load Drivers Procurement Notes

Verify the complete part number including the suffix GE2 to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm that the required package variant matches the 8-TSSOP-BJ specification for your PCB layout. Ensure input logic levels are compatible with the active-low control requirement before integration into the design.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when multiple low-current high-side switches are required in a compact form factor. The 600 mA current limit suits standard USB peripherals and low-power loads. Consider the 90 mΩ on-resistance for thermal management calculations. Verify that the 2.7 V minimum supply voltage aligns with the system's available rail.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the BD82039 series of high-side switches. It is distinct from single-channel variants like the BD82043 and multi-channel models with higher current ratings. The TSSOP-B8J package provides a small footprint suitable for space-constrained portable devices. It serves as a dedicated solution for distributing power to multiple low-power loads from a single supply line.

Power Distribution Switches, Load Drivers Replacement Considerations

Direct substitutes within the same family may include other BD82039 variants if pin compatibility is confirmed. Single-channel alternatives require additional board space. Verify that any replacement maintains the 600 mA current limit and 2.7 V–5.5 V operating range to ensure functional equivalence.
